The SparkFun RedBot Mainboard is an Arduino-compatible robotic development platform that combines an ATmega328P microcontroller with a TB6612FNG dual DC motor driver on a single board — no shield stacking required. It programs over USB via the Arduino IDE using the Optiboot (Uno) bootloader.

The board includes headers for optional RedBot sensor and servo add-ons, an XBee socket for wireless control, and a barrel jack or 2-pin header for 6–9 V power input. Pair it with a chassis and sensors to build a fully customisable robot.

Key Features

• ATmega328P – Arduino Uno-compatible, pre-programmed with Optiboot bootloader
