2 Introduction
cB-OBS418 is a small size Classic Bluetooth module based on the Texas Instrument CC2560 radio chip and a
ST Microelectronics STM32F10x microprocessor. The module is a direct replacement of the cB-OBS410
module. The module is available in different configurations (see
Product Variants
) with
internal antenna
or a
U.FL. connector for connecting an
External antenna
.
The hardware of the cB-OBS418 products are referred as cB-0946 and the module is Type Approved with the
type name cB-0946.

3 Electrical Interface and Connectors
This section describes the signals available on the module interface connectors. There are three ways to
connect to the OEM Serial Port Adapter:
Via the PCB solder pads on the edge of the PCB, J6 (see Figure 3). See Section "Using
the J6 PCB
solder pads
" for more information.
Via the 2x20-pin 1mm pitch board-to-board (one piece part) connectors, J2 through J3. The J2 to J3
connectors on the OEM Serial Port Adapter exist on the module only as a mating PCB-layout pattern
(see Figure 3). See Section "
Using the J2/J3 Board-to-Board Connectors
" for more information.
Figure 3: The solder pads J6 are available on the long edges of the bottom side of the PCB. The
board-to-board connector pads J2-J3 are located between the mounting holes.
