CBM-003 PRELIMINARY DATASHEET

Description

CBM-003 is a Class 2 embedded Bluetooth module

designed to be integrated into LED drivers, diﬀerent

lighting control applications, light ﬁxtures, and LED

bulbs. It is pre-programmed with Casambi’s proprietary

ﬁrmware making it completely compatible with other

Casambi enabled devices.

CBM-003 is controlled wirelessly with Casambi

smartphone and tablet (“smart device”)

applications using Bluetooth protocol. Devices

form a self-healing and self-organizing wireless

mesh network automatically so that a large number

of luminaires can be controlled from any point.

No external gateway module is needed.

CBM-003 contains a powerful 32-bit ARM® Cortex®

-M4 CPU and a 2.4 GHz transceiver with an onboard

antenna. Diﬀerent external components, such as

motion detectors, ambient light sensors, and PWM

circuits can be interfaced with the module using its

12 general-purpose I/O pins.

CBM-003 can be mounted both in horizontal and

vertical positions, making it very versatile for

projects with diﬀerent form factors.

1. Operation Casambi CBM-003 is an embedded wireless module with a powerful 32-bit ARM® Cortex® -M4 CPU and a 2.4 GHz transceiver with an onboard antenna. It can be integrated, for example, into an LED driver, a light fixture, LED bulb, or any sensor. The CBM-003 has a total of 12 GPIO pins, which can be configured to perform various tasks, such as SPI, TWI (I2C compatible), UART, 8 PWM outputs, and 4 channel Analog-to-Digital Converter input. ADC input channels have fixed GPIO pins.

3. System blocks 3.1 General Purpose I/O (GPIO) The CBM-003 has 12 General Purpose I/O pins. Some of them are High-drive (9 mA) while some are standard-drive (2 mA).
PAGE 5
4. Serial Interfaces The CBM-003 can be connected to an external MCU through its Casambi proprietary interface extension interface, which supports SPI, TWI, and UART. All extension interface signals shall be connected to High-drive pins if data rate exceeds 10 kHz. UART/SPI/ TWI interfaces are dedicated for this purpose and are not available for generic use outside of Extension Interface Protocol without special arrangements from Casambi Technologies.

7. Module installation placement The CBM-003A uses an antenna that operates best when the CBM-003A module is properly grounded on the carrier PCB ground plane and has three extra grounding terminals for this purpose. However, the module can be used without connecting these terminals, but it may decrease antenna performance. A GNDs for antenna B The antenna side ("A") is located at the edge of the carrier board. The CBM-003 antenna is not affected by surrounding materials.
