CBM-002A/B
4 Operation
Casambi CBM-002A/B is an embedded wireless module with a powerful 32-bit ARM® Cortex™-M4 CPU and a
2.4 GHz transceiver with on-board antenna and optional matching circuitry. It can be integrated, for example,
into an LED driver, a light xture or an LED bulb.
CBM-002A/B has total of 12 GPIO pins, which can be congured to perform various tasks, such as SPI, TWI (I2C
compatible), UART, 4 channel PWM output and 3 channel Analog-to-Digital Converter input. Only the ADC
input channels have xed GPIO pins. Other functions can be freely congured to any GPIO pin.
CBM-002A/B is controlled wirelessly by a smart device with Casambi application. Multiple Casambi units form
automatically a mesh network, which can be controlled from any point. The network communicates directly
with the smart device using Bluetooth 4.0. No external gateway device or Wireless LAN network is needed.
CBM-002A/B has an integrated 2,4 GHz antenna. This will have to be taken into account when the device is
integrated to any environment. See chapter “14.5 Mounting” for further instructions.
The module can be operated also from a traditional on/off wall switch. By icking the switch on and off the
user can select different pre-set modes. These modes can affect one or several devices on the network. This
way the user does not have to have the smart device at hand all the time in order to select the desired settings
or modes. This feature requires an external electrolytic capacitor to supply power during power-off stage as
well as a power-on detection circuitry.
A large number of different setting of CBM-002A/B can be congured in Casambi Admin webpages and taken
into use without a need to re-program the module. These settings include, for example, I/O pin mapping,
PWM, push buttons, etc.

CBM-002A/B
6 System Blocks
CBM-002A/B has 12 General Purpose I/O pins. Each GPIO can be accessed individually and each has the fol-
lowing features:
• Input/output direction
• Congurable output drive strength
• Internal pull-up and pull-down resistors
• Buffered inputs
• Trigger interrupt on all pins (rising edge, falling edge, any change)
• Serial interface and PWM output can be freely congured to each pin
GPIO pins 0-3 also supports analog input signals when an internal Analog-to-Digital Converter (ADC) is used.
The up to 12-bit Analog-to-Digital Converter enables sampling of up to 4 external signals (GPIOs 0-3) through
a front-end multiplexer. The ADC has congurable input and reference prescaling, and sample resolution (8,
10, and 12-bit).
There are two options for the voltage reference:
• Internal 1,20 V reference
• VCC with 1/3 prescaling
Analog inputs can have a congurable gain of 1/6, 1/5, 1/4, 1/3, 1/2, 1, 2 and 4. The suitable voltage range
for ADC input is 0 V - VCC.
Any GPIO pin can be congured to output PWM signal. Up to 4 PWM channels can be used simultaneously.
PWM frequency can be determined freely up to 40 kHz. PWM frequency is the same with all PWM channels.
The maximum resolution is 400-1600 steps and it depends on the PWM frequency.
The PWM signal is logic level (max. VCC) and it has driving capacity from 4 mA (standard) up to 14 mA (high-
drive). An adjustable analog voltage (0 V - VCC) can be derived from the PWM signal by an external RC lter.
A 10 kHz PWM signal together with a 10kΩ + 2,2 µF RC filter can be used as a starting point. Depending on
the application, it may be necessary to use an operational amplifier as a buffer stage.

CBM-002A/B
7 Serial Interfaces
CBM-002A/B supports a 3-wire (SCK, MISO, MOSI) bidirectional SPI bus with fast data transfers to and from
multiple slaves. CBM-002A/B acts as a master and it provides a simple CPU interface which includes a TXD
register for sending data and an RXD register for receiving data. These registers are double-buffered to en-
able some degree of uninterrupted data ow in and out of the SPI master.
Each of the slave devices requires an individual chip select signal which can be connected to any available
GPIO pin. The SPI master does not implement support for chip select directly. Therefore, the correct slave
must be selected independently of the SPI master.
The GPIOs used for each SPI interface line can be chosen from any GPIO on the module and are indepen-
dently congurable. This enables great exibility in module pinout and enables efcient use of printed circuit
board space and signal routing.
The SPI peripheral supports SPI modes 0, 1, 2, and 3.
7.1 Serial Peripheral Interface (SPI)
The Two-Wire Interface (I2C compatible) can interface a bidirectional wired-AND bus with two lines (SCL,
SDA). The interface is capable of clock stretching and data rates of 100 kbps and 400 kbps are supported. The
TWI transmitter and receiver are single buffered.
The GPIOs used for each Two-Wire Interface line can be chosen from any GPIO on the module and are in-
dependently congurable. This enables great exibility in module pin-out and enables efcient use of board
space and signal routing.
7.2 Two-Wire Interface (TWI)
The Universal Asynchronous Receiver/Transmitter offers fast, full-duplex, asynchronous serial communication
with built-in ow control support in HW up to 1 Mbps baud. Parity checking and generation for the 9th data
bit are supported.
The GPIOs used for each UART interface line can be chosen from any GPIO on the module and are indepen-
dently congurable. This enables great exibility in module pinout and enables efcient use of board space
and signal routing.
7.3 Universal Asynchronous Receiver/Transmitter (UART)
CBM-002A/B can be connected to an external MCU through its extension interface, which supports SPI, TWI
and UART. Through this interface it is possible to, for example, gather information from sensors through
Casambi network.

14 Application Information
Casambi has developed a solution for controlling lighting with only a traditional on/off wall switch. By default,
the wall switch can be used to dim the lights, but different settings can be selected from Casambi App, such as
selecting a pre-set mode. With Smart Switching feature, multiple lights can be controlled from a single switch.
Smart Switching feature is used by icking the wall switch quickly off and on.
Smart Switching is a function which requires an external electrolytic bypass capacitor and a power-on detec-
tion circuitry to work. The external electrolytic capacitor is needed to supply the necessary operating voltage
for the module during power-off stage. It can be either an external capacitor just for the CBM-002A/B, or
it can be a part of a larger power supply on the host board. If the capacitor is dedicated just for the CBM-
002A/B, the minimum required capacitance is 1200 µF. It is advisable to connect the capacitor before any
voltage regulation for larger voltage drop.
Even if Smart Switching feature is not used, the correct use of CBM-002A/B still requires the power-on detec-
tion and the external capacitor. These are needed so that the module can inform Casambi network when its
power is cut off. The external capacitor will provide power to the module a short time after the power has
been switched off. A suitable time for Smart Switching is 1,5 seconds and without Smart Switching 0,5 sec-
onds. The external capacitor will have to be sized according to these requirements.
It is a good practice to use a capacitor with temperature range up to 105°C.

CBM-002A/B
Page 14 of 25
In order to operate correctly, the Casambi network will have to know if the power has been switched off from
some unit. For this reason, the unit will have to know when its power has been switched off. This is done by a
power-on detection together with an external capacitor (see previous chapter).
In case of CBM-002A/B the power-on detection is a signal that is connected to any GPIO pin. The signal can
be one of the following four types:
- constant high signal when power is present, low signal when power is absent
- constant low signal when power is present, high signal when power is absent
- 50/60/100/120 Hz square wave signal when power is present, constant low signal when power is absent
- 50/60/100/120 Hz square wave signal when power is present, constant high signal when power is absent
The power-on signal can be derived from either DC voltage or AC mains voltage. If the host application is
mains powered, so called Zero Detect circuitry shall be designed. The Zero Detect circuitry is connected to
mains voltage and it detects when the voltage crosses the zero point. This information is needed to determine
when the wall switch has been switched off and when it is switched back on. In mains voltage powered ap-
plication, CBM-002A/B requires one or two Zero Detect pulses on each mains cycle, so the mains voltage can
be half- or full-wave rectified. Also the use of a schmitt trigger is strongly advised in order to get clean pulses.
No application schematics of the Zero Detect circuitry is provided on this datasheet. This is because the ap-
plication and the surrounding electronics may vary greatly which makes it impossible to provide a solution
that works on every application. The designer of the host system will have to design a suitable Zero Detect
circuitry. If the host system power supply is isolated, the Zero Detect signal will have to be isolated as well.
Extreme caution will have to be used when working with Zero Detect since potentially lethal mains voltages
are involved.
The voltage level of the Zero Detect signal will have to be suitable for CBM-002A/B. Zero Detect signal can be
connected to any free GPIO pin on CBM-002A/B.
Use of the external capacitor and Zero Detect circuitry is strongly advised. In addition to Smart Wall Switch
feature they enable faster response to the power-off condition. When the mains voltage is cut out from the
device with CBM-002A/B, the capacitor supplies enough power for the module to send status update to the
network. This way the status of the module is immediately updated to offline on the Casambi application.
If the external capacitor and Zero Detect circuitry is omitted, the module will have to send status information
to the network periodically which causes a delay to the status update on the application as well as unneces-
sary traffic on the network.

CBM-002A/B
Page 15 of 25
CBM-002A/B is available in two different antenna versions. CBM-002A is equipped with an on-board SMD
chip antenna and CBM-002B is equipped with a 1/4 wavelength dipole antenna. Usually CBM-002B offers
better range, but CBM-002A is more compact solution.
CBM-002B is delivered with the antenna detached, so the antenna will have to be soldered in place before
taking the module into use. This is because the antenna can be soldered in vertical or horizontal position. The
host device application determines which antenna orientation is more suitable. Read 14.5 CBM-002B Antenna
for more information.

CBM-002A/B
Page 16 of 25
CBM-002A/B has two sets of soldering pads, which allow it to be mounted both in horizontal and vertical
position. In some application, such as LED drivers, there are large components which could affect the antenna
performance greatly if the module is mounted at the bottom of the device horizontally on the main PCB. Also,
horizontally mounted module has much larger footprint compared to vertically mounted module.
14.4 Mounting
CBM-002B is delivered with the antenna detached. The antenna is a 27 mm long single strand copper wire
and it can be soldered in horizontal or vertical orientation, depending on the best suitability for the host ap-
plication.
The antenna can be bent to t the host application better. However, there are some guidelines that need to
be taken into consideration.
1. Make sure that antenna is not in contact with any kind of metal.
2. The antenna should be places as far away from any metal structures as possible.
3. The tip of the antenna is especially sensitive for close by metals.
4. The less bending is done on the antenna, the smaller impact it haves on the range.
4. Do not use any other kind of antenna, or do not cut or otherwise modify the delivered antenna.
The antenna is soldered onto the left side solder pad (the pad closer to the antenna matching components).
When soldering the antenna in horizontal position, for correct operation, place the antenna so that it lls the
whole length of the soldering pad. This way the antenna extents over the edge of the module by 23,5-24,0
mm.
When the antenna is soldered in vertical position, solder it so that the antenna rises 23,5-24,0 mm over the
PCB surface. Cut the antenna wire from the bottom side to the desired length. This cutting does not affect
the performance or approvals.
Important!
CBM-002B has been certied with the supplied antenna and modifying it beyond the instructions given in this
datasheet will void the certication.

CBM-002A/B
Page 17 of 25
When CBM-002A/B is mounted in a horizontal position it is soldered in by using the soldering pads on both
long sides of the module. The soldering pads are designed so that the module can be both hand and reow
soldered.
When mounted in a horizontal position, there are two mandatory keep-out areas involved. One is for antenna
and the other is for bottom side soldering pads at the narrow end of the module. These pads are used for
vertical assembly.
For the CBM-002A, the antenna keep-out applies to all layers of the mother board. There shall not be any
components, traces, pads or copper areas in any layer within the keep-out area. The same applies to other
metals as well, such as the enclosure of the product, xing screws, etc.
The keep-out area for the soldering pads applies only to the outer surface of the mother board.
14.4.1 Horizontal Mounting
1) This keep-out area will have to be kept clear from any parts, traces and copper on all layers.
2) This keep-out area applies only to the layer closest to the module.
3) If CBM-002B antenna is soldered vertically, this keep-out area will have to be a hole. Otherwise keep-out
area applies only to the layer closest to the module.

For such cases the module can be mounted in vertical position, either by soldering it to a 1,27 mm pitch 2-row
pin header, or by soldering the module directly into a routed slot on the main PCB.
When mounted in horizontal position there will have to be two keep-out areas; one for the antenna area and
one for the unused pads used for vertical assembly.

CBM-002A/B can be mounted in vertical position by using the soldering pads on the narrow end of the mod-
ule. There are two methods of soldering the module in vertical position. It can be either soldered between pin
rows of a 2-row 1,27 mm pin header (2 x 8P) or it can be soldered in a 0,9 mm slot routed on the main board
with soldering pads at the edge of the slot. The thickness of the module printed circuit board is 0,85 mm.

16.5 Cleaning
In general, cleaning the populated modules is strongly discouraged. Residuals under the module cannot be
easily removed with any cleaning process. Use of “No Clean” soldering paste is strongly recommended, as it
does not require cleaning after the soldering process.
16.3 Hand Soldering
Hand soldering is possible. When using a soldering iron, follow IPC recommendations (reference document
IPC-7711).
16.4 Rework
The module can be unsoldered from the host board. Use of a hot air rework tool should be programmable
and the solder joint and module should not exceed the maximum peak reow temperature of 250°C.
If temperature ramps exceed the reow temperature prole, module and component damage may occur due
to thermal shock. Avoid overheating. Never attempt a rework on the module itself, (e.g. replacing individual
components).
