ATmega328P Bluetooth Control Board

Project overview

General-purpose control board built around an ATmega328P, the same microcontroller used in the Arduino Uno, paired with an external Bluetooth Low Energy module for wireless communication and an onboard battery management system for portable, rechargeable operation.

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 ATmega328P, External BLE Module and Battery Management, 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.
