Modular Fab Stepper Driver

This is a Fab-Labbable (i.e. easy-to-pcb-mill) design for a networked stepper driver. Check the dev log for more details.

motor

This uses the SAMD21E18 microcontroller, 2x A4950 H-Bridges to drive, and is connected to osap networked controllers using the uart-clocked bus data link, an RS-485 powered deterministic bus.

Building Fab-Step

Circuit files are available here.

BOM

I have published an online Bill of Materials, here or you can download the spreadsheet or csv.

Firmware

Firmware for the motor driver is here and uses platform.io to run, see this guide to build and load code.
