Robotics Control Board

Project overview

Dual RP2040 (the same chip used in the Raspberry Pi Pico) robotics control board with RJ45 host connectivity, multiple sensor I/O, and flexible 5V, PoE, or battery power input.

Engineering approach

Robotics controllers need to juggle real-time control loops, sensor input, and actuator output without the layout introducing timing jitter or noise into the control path. On this board, that translates into a component set built around 2x RP2040 and Dual RJ45, with layout and stack-up decisions driven by motor drive integrity, sensor fusion timing, and expansion headers that keep the platform flexible.

Technical specification

Engineering focus

This portfolio project demonstrates CircuitNexa's electronics engineering and PCB design work in the robotics space. The design shown here is part of a broader portfolio spanning schematic capture, PCB layout, embedded firmware, prototyping, and support through to manufacturing.
