CBM-003B/C PRELIMINARY DATASHEET

Description

CBM-003B/C 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-003B/C 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-003B/C 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-003B/C can be mounted both in horizontal and

vertical positions, making it very versatile for

projects with diﬀerent form factors.

1. Operation Casambi CBM-003B/C 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-003B/C 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-003B/C 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-003B/C 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. Mounting 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-003B/C has two sets of soldering pads, which allow it to be mounted both in horizontal and vertical position. Inn vertical position module can be installed either by to a 1,27 mm pitch 2-row pin header, or by soldering the module directly into a routed slot on the main PCB. 7.
PAGE 11
7.2 Vertical mounting CBM-003B/C can be mounted in vertical position by using the soldering pads on the narrow end of the module. 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 (+/- 0,1mm).

9. Soldering 9.1 Leadfree Reflow Soldering Recommended temperature profile for leadfree reflow soldering Maximum number of reflow cycles: 2 Opposite side reflow is prohibited due to the module’s weight. (i.e. you must not place the module on the bottom / underside of your PCB and reflow). 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.

. Antenna versions CBM-003B/C is available in two different antenna versions. CBM-003B is equipped with an on-board SMD ceramic chip antenna and CBM-003C is equipped with a 1/4 wavelength dipole antenna. Usually CBM-003C offers better range, but CBM-003B is more compact solution. CBM-003C 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.
