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 1. 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 microcontroller, 2.4GHz transceiver and several peripheral blocks. These blocks include PWM, SPI, I2C, UART and GPIO (i.e. pushbutton, relay control).

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.

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.

RFM-CSB-3 4. ZERO CROSS DETECTION (ZD) 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.
