About the ESP32-Stepper-Motor-Breakout-Board

ESP32-Stepper-Motor-Breakout-Board is an open source PCB design by KevinCKHo, published on GitHub. It is a 2-layer board measuring 85 × 110 mm, with 31 components from 23 distinct parts.

By type, the board carries 20 connectors, 7 resistors and 4 capacitors.

It belongs with the robotics & motion, dev boards & breakouts and sensors designs in this gallery.

From the project

A Wi-Fi controlled, 4-axis stepper motor controller built around an ESP32 on a custom breakout PCB. It was designed to drive a motorized microscope stage (the Microscope Stage Mover).

A Wi-Fi controlled, 4-axis stepper motor controller built around an ESP32 on a custom breakout PCB. It was designed to drive a motorized microscope stage (the Microscope Stage Mover).

The ESP32 creates its own Wi-Fi access point and serves a web dashboard. From the dashboard you can jog each axis with sliders, trigger an emergency stop, and watch temperature and humidity live.
