info@casambi.com tel. +358 10 501 2950 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 fixture or an LED bulb. CBM-002A/B has total of 12 GPIO pins, which can be configured 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 fixed GPIO pins. Other functions can be freely configured 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 flicking 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 configured 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. 5 Block Diagram Crystal, 32 MHz VCC GND GPIO0 GPIO11 32 bit Cortex M4 RF-MCU Matching network SWDCLK SWDIO/nRESET Picture 1.

Each GPIO can be accessed individually and each has the following features: • • • • • • Input/output direction Configurable 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 configured to each pin GPIO pins 0-3 also supports analog input signals when an internal Analog-to-Digital Converter (ADC) is used. 6.2 Analog-to-Digital Converter (ADC) 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 configurable 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 configurable 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. 6.3 PWM Output Any GPIO pin can be configured 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 (highdrive). An adjustable analog voltage (0 V - VCC) can be derived from the PWM signal by an external RC filter. 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. +3 VDC CBM-002A/B 10 kHz PWM 0-3V analog GPIOx G3,33 0-10V output Picture 2.

Through this interface it is possible to, for example, gather information from sensors through Casambi network. 7.1 Serial Peripheral Interface (SPI) 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 enable some degree of uninterrupted data flow 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 independently configurable. This enables great flexibility in module pinout and enables efficient use of printed circuit board space and signal routing. The SPI peripheral supports SPI modes 0, 1, 2, and 3. 7.2 Two-Wire Interface (TWI) 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 independently configurable. This enables great flexibility in module pin-out and enables efficient use of board space and signal routing. 7.3 Universal Asynchronous Receiver/Transmitter (UART) The Universal Asynchronous Receiver/Transmitter offers fast, full-duplex, asynchronous serial communication with built-in flow 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 independently configurable. This enables great flexibility in module pinout and enables efficient use of board space and signal routing.

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 flicking the wall switch quickly off and on. Smart Switching is a function which requires an external electrolytic bypass capacitor and a power-on detection 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 CBM002A/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 detection 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 seconds. 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.

Powering CBM-002A/B with an external capacitor for Smart Switching Page 13 of 25 Casambi Technologies Oy Linnoitustie 4 A 02600 Espoo, Finland www.casambi.com info@casambi.com tel. +358 10 501 2950 CBM-002A/B 14.2 Power-On Detection 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 application, 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 application 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 unnecessary traffic on the network.

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. Picture 7. CBM-002A on left and CBM-002B on right Page 15 of 25 Casambi Technologies Oy Linnoitustie 4 A 02600 Espoo, Finland www.casambi.com info@casambi.com tel. +358 10 501 2950 CBM-002A/B 14.3.1 CBM-002B Antenna 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 application. The antenna can be bent to fit 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 fills 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 certified with the supplied antenna and modifying it beyond the instructions given in this datasheet will void the certification. Picture 9. Soldered CBM-002B antennas. 14.4 Mounting 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.

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. 14.4.1 Horizontal Mounting 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 reflow 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, fixing screws, etc. The keep-out area for the soldering pads applies only to the outer surface of the mother board. 10,00 4,75 1) 3) 1,00 6,00 2,00 3,20 4,75 2) 2,00 2x Ø3,00 1,00 1,00 CBM-002 20,00 1,50 3,00 CBM-002B 20,00 1,50 2) 0,20 2,40 3,00 11,00 13,70 2) 0,20 2,40 11,00 13,70 Picture 9.

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 reflow temperature of 250°C. If temperature ramps exceed the reflow temperature profile, 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). 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. 17 Compliance Information Compliance Information Radio Environmental USA (not yet approved) FCC Part 15 Subpart C FCC ID (CBM-002A): 2ALA3-CBM002A FCC ID (CBM-002B): 2ALA3-CBM002B Canada (not yet appr.)
