FlexBench
Header I/O pins on the back of the FlexBench are Samtec TFM-120-02-L-DH. If a custom board is desired we recommend:
- Download the design files for the breakout board.
- You can swap the Samtec SFM counterpart if desired. An example part number would be SFM-120-xx-x-x-D(H) where x is selectable based on your application. You can design horizontal or vertical boards.
- You may want to add bulk capacitors and overvoltage protection to your custom circuit if desired.
- Use the provided mount holes to secure your PCB.
- Check the positioning of your design using the provided CAD model.
- You can get the board manufactured and assembled at your favourite PCBA supplier.
