B-SoM setup
This page walks you through unboxing and setting up a B-Series SoM (B-SoM), a cellular M.2 system-on-module with Bluetooth LE designed for IoT products. By the end, the B-SoM will be powered up and ready to add to your Particle account.
Unboxing

The B-SoM box contains:
- B-SoM system-on-module
- Cellular antenna (PARANTC41EA)
- Bluetooth antenna (ANT-FLXV2)
Note:
The M.2 SoM breakout board and the M.2 evaluation board are sold separately.
Choose a board
You can set up the B-SoM on either of these boards:
- The M.2 SoM breakout board, which gives you the most flexibility when evaluating and designing custom hardware
- The M.2 evaluation board, which is older hardware
Using the M.2 SoM breakout board

- Insert the B-SoM into the M.2 socket on the breakout board.
- Connect the cellular and Bluetooth antennas.
- Install the power module on the breakout board.
- Power the board with the supplied AC/DC power adapter.
- Plug in the battery.
- Connect the breakout board to your computer with a USB cable.
For more details on the layout and specifications, see the M.2 SoM breakout board datasheet.
Using the M.2 evaluation board

For detailed instructions on setting up the B-SoM on the M.2 evaluation board, see the M.2 evaluation board datasheet.
