The Balboa 32U4 is a small, user-programmable balancing robot based on the Arduino-compatible ATmega32U4 AVR microcontroller and featuring two H-bridge motor drivers, quadrature encoders for closed-loop motor control, a full inertial measurement unit (3-axis accelerometer, gyro, and magnetometer) for estimating orientation and balancing, and an optional interface for connecting a Raspberry Pi to make a Raspberry Pi-controlled balancing robot. The control board includes a powerful 5 V switching step-down regulator that can supply up to 2 A continuously, along with a versatile power-switching and distribution circuit. Three on-board pushbuttons offer a convenient interface for user input, while indicator LEDs, a buzzer, and a connector for an optional LCD (not included) allow the robot to provide feedback.
This is a kit; assembly (including soldering) is required. Motors and wheels are not included so you can choose your own to personalize your robot; see below for details. Balboa runs on six AA batteries (not included), and a USB A to Micro-B cable (not included) is required for programming.
