RFM-CSB-3
Features of the Module include:
The RFM-CSB-3 module
The BLE mesh Network
• Wireless Bluetooth 4.0 Mesh Network
• Free Casambi lighting control app
• Four programmable control lines
• Easy integration with card-edge SMT
connector interface
• FCC & CE certified
The Bluetooth 4.0 mesh network operates
without the need for additional controllers
or gateway units. The 200ft (60m) open air
functioning distance enables a wide range
of lighting arrangements while the exclusive
Casambi-Bluetooth connection prevents the
lighting system from interfering with other
Bluetooth networks.
The RFM-CSB-3 is a class 2 Bluetooth 4.0
module for integration into lighting fixtures,
LED drivers or other lighting controls. The
module contains a powerful 32 bit ARM®
CortexTM microcontroller and 2.4GHz
transceiver with on-board antenna. Four logic
level control signals are available on the 6-pin
card edge connector. The module operates
exclusively through the Casambi app (free on
IOS and Android).

RFM-CSB-3
OPERATION
The RFM-CSB-3 is an embedded wireless module intended to operate in conjunction with
the Casambi Lighting control app. Four configurable I/O lines interface to the host device for
control of up to 4 independent lighting channels.
A highly integrate SOC (system on chip) contains a 32 bit ARM® CortexTM microcontrol-
ler, 2.4GHz transceiver and several peripheral blocks. These blocks include PWM, SPI, I2C,
UART and GPIO (i.e. pushbutton, relay control). These can be configured in Casambi Admin
webpages and taken into use without a need to re-program the module.
The default factory configuration for the I/O is four PWM outputs @ 1.2kHz

RFM-CSB-3
3. PERIPHERAL BLOCKS
a. PWM
Any GPIO pin can be configured to output a PWM signal. Up to 4 PWM channels can be used
simultaneously. PWM frequency can be determined freely up to 40 kHz. By default the PWM
frequency is the same for 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 0,5 mA (standard) up to 15 mA (high-drive).
b. SPI
RFM-CSB-3 supports a 3-wire (SCK, MISO, MOSI) bidirectional SPI bus with fast data
transfers to and from multiple slaves. RFM-CSB-2 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.

RFM-CSB-3
c. I2C
This two-wire interface uses clock (SCL) and bidirectional data (SDA). The protocol makes it
possible to interconnect up to 128 individually addressable devices. The interface is capable
of clock stretching and data rates of 100 kbps and 400 kbps are supported.
The GPIOs used for each Two-Wire Interface line can be chosen from any GPIO on the module
and are independently configurable.
d. UART
The Universal Asynchronous Receiver/Transmitter offers fast, full-duplex, asynchronous serial
communication with built-in flow control (CTS, RTS) 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.
e. GPIO
Each of the four I/O can also be configured for alternate input/output functions. Casambi
supported functions include:
• Pushbutton input • Relay control output • Zero Detect Input • Fixed “idle” state output
The I/O can be further tailored using options such as:
• Input/output polarity • Output drive strength • Internal pull-up and pull-down resistors

RFM-CSB-3
The RFM-CSB-3 can be configured to detect the zero crossing point of an AC signal. This is
necessary to take advantage of Casambi’s “Smart Switching” feature. This looks for a pattern
of on-off cycles (quickly switching AC source on & off) in order to implement specific modes or
settings.
For proper Smart Switch operation, local VCC of the module must be kept alive during loss of
AC for 1.5 seconds. A 1200uf cap on VCC is typically recommended.
It is the responsibility of the host system designer to create the zero detection circuit and it’s
output needs to be compatible with logic level inputs of the RFM- CSB-1 (see specifications
section). ZD polarity and phase are adjustable in the Casambi admin webpages.
If Smart switching is not required, it is suggested to configure the ZD input for online/
offline detection. This allows the module to notify the network when it goes offline. This
reduces network bandwidth as it will not be repeatedly polling for a device that is no longer
responding. Local VCC must be kept alive for at least 500ms to support this feature.
