XMOS/Pololu Motor Interface Board
I’m currently designing a motor interface board to go between the various XMOS development boards and the Pololu Dual MC33926 Motor Driver Carrier. These are the initial board designs, though I haven’t fully decided whether to include the connections to the XMOS 5V0 and 3V3 lines.
Also note that the autorouter got a little crazy in some places trying to make this work with only 2 layers. There are some places that need cleaning up (e.g. the 3V3 line near the right-hand side).
