2 layer board of 0.70x0.91 inches (17.78x23.14 mm).

An adapter to allow a Pololu DRV8825 or Panucatt SD6128 driver to be used in a Mightyboard. You will get 1/16 microstepping with either of these.

Note: do not use with Pololu a4988s, the microstep settings aren’t right. But why would you want to? Stock BotStep style drivers are already a498x, just use those.

Digikey BOM:

  • WM50016-17-ND – 17 position male header (1 per board, cut to 8,8,1)

  • S7041-ND – 8 position female header (2 per board)

  • 929974E-01-01-ND – 1 position female header (optional, 1 per board IF you want to use digipot vref instead of trim pot)
