Stepper PCB
Completed: October 2025
Schematic from Pololu
Description:
I designed, routed, and milled a compact PCB that creates a seamless interface between the NEMA-17 stepper motor, Pololu A4988 driver carrier, and Seeed Xiao ESP32-C3 microcontroller. The board is completely plug-and-play: just insert the A4988 and the Xiao and solder the two motor coil pairs. All power routing, signal traces, and protection components are integrated into the PCB, making this super compact and convenient for prototyping.
