SamD21 TM

Options

Firmware :
IO Headers :

The SamD21 TM board brings you the power of a SamD21 in a small form factor, and has an on-board connector that allows to connect it to Thrustmaster Wheel bases. This allows you to build custom wheels without  USB cable, by getting power supply from the base and sending back states of buttons/encoders/etc (use our dedicated cable for an easy connection).

 

21 inputs are handled on the base :

 

This board is a modified SamD21 Mini board : The A2 pins is connected to the MOSI pin, so that all the connexions with the base are available on the ICSP header. The pins D8, D9, A2, MOSI, MISO and SCK are reserved and not available.
