1 Overview
This chapter gives a short overview of the VAR-EXT-CB105 extension board.
1.1 General Information
The VAR-EXT-CB105 extension board is an add-on board, which plugs into the
VAR-xxCustomBoard extension connectors. The VAR-EXT-CB105 exposes more
than 90% of the VAR-SOM-xx interfaces into 2.54mm pitch through-hole
connectors. The VAR-EXT-CB105 standard headers provide a fast & easy way for
adding additional custom hardware to the VAR-xxCustomBoard.
VAR-EXT-CB105 features:
1. RS232 Transceiver (DTE)
2. RS485 Transceiver
3. CAN BUS Transceiver
4. General purpose 1.8V to 3.3V level shifter
5. JTAG interface adapter
