-# DDMC Stepper Daughter
+# Squidworks Moduleboard Daughter: Stepper
 
-TMC262, 4 PN Pairs and an SPI encoder breakout. 
+This is a stepper driver for the [squidworks](https://gitlab.cba.mit.edu/squidworks/squidworks) project, that lives with one of the [moduleboards](https://gitlab.cba.mit.edu/squidworks/moduleboard-atsamd51) for the same. It uses a TMC262 bipolar chopper driver with 4 PN Pair FETs rated for ~ 8A, and features an SPI encoder breakout. Schematic and Board files are available in this repo. A revision is in the works for more intelligent connector placement.
