OLS425 / OLP425 series - Electrical Mechanical Data Sheet
The platform module cB-OLP425 is a hardware platform based on the Texas Instruments CC2540
system-on-chip (256 kB flash memory and 8 kB SRAM).
The TI chip runs both application and the Bluetooth low energy protocol stack. The
TI Bluetooth low energy software stack and tools
includes object code with the latest BLE protocol stack supporting multiple connections, sample projects and applications covering an extensive set of profiles with source code. Please note that this package is not provided by u-blox.
The cB-OLP425 sample code package includes sample projects for accessing the LEDs, temperature sensor and accelerometers.
All embedded software is developed using
IAR Embedded Workbench for 8051
.
NOTE
Software/firmware support is not included by u-blox. To sign a support agreement for software support or to discuss a full implementation project please contact us.
3 Electrical Interface and Connectors
3.1 Electrical Interface and Connectors on the cB-OLP425 Platform
3.1.1 cB-OLP425 Connector Interfaces
This section describes the signals available on the cB-OLP425 platform. There are three ways to connect to the cB-OLP425 platform:
Via the PCB solder pads on the edge of the PCB, J6 (see Figure 6). See Section " Using the J6 PCB solder pads " for more information.
UBX-15016241 - R14 Production Information

OLS425 / OLP425 series - Electrical Mechanical Data Sheet
Via the JST connector, J8 (see Figure 7).
The JST connector is a 6 poles wire connector. The pitch is 1mm. The manufacturer of the mounted connector is JST and the part number is SM06B-SRSS-TB. The SM06B-SRSS-TB connector is mated with the wire connector SHR-06V-S from JST. Other connector options are also available from JST.
JST Connector
The JST connector does NOT contains a UART interface in contrast with many other ublox/connectBlue Serial Port Adapters OEM modules. The JST connector is a debug, firmware upgrade and IO interface on the cB-OLP425 modules. See the u-blox CC
Debugger Adapter Board - User Guide [8] and cB-OLP425 Development Kit Getting
started
[5] documentation for more info about the debug interface and how to use it.
Notice that the TI CC Debugger Adapter Cable (cB-ACC-71) included in the
Development kit can NOT directly be connected to the cB-OLP425 if the module at the same time has voltage supplied from another source e.g. a battery. A voltage supply collision will occur which could damage the electronics/battery because the CC
Debugger also includes a voltage supply pin which is connected to the voltage supply pin on the J8 JST connector via the adapter cable. It is strongly recommended to use the CC Debugger Adapter Board instead of the cB-ACC-71 cable.
Via the 4x1 through holes row J7 (see Figure 7) for solder wires or through holes components to the board (1.27mm pitch).
Figure 6: The solder pads J6 are available on the long edges of the bottom side of the PCB.
