About the Robodev Actuators PCB

Robodev Actuators is an open source PCB design by alexbnz-1, published on GitHub under the MIT license. It is a 4-layer board measuring 88 × 83.5 mm, with 113 components from 25 distinct parts.

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

From the project

A repository for the development of a robotics development board designed to aid in the development of robotics projects

An open-source STM32-based robotics carrier board with integrated WiFi. Plug in power, plug in your motors and sensors — that's it. No breadboard, no stacked breakout boards, no wiring harness.

Five independent rails from a single XT60 input with reverse polarity protection (IRF4905 P-channel MOSFET) and a slide switch.

VMOT and VSTEP are separate adjustable bucks so DC motors and steppers can run at different voltages simultaneously.
