Hiwonder UNO Expansion Board Compatible with Arduino, Supports Motor and Servo Control, Bluetooth Communication, and Sensor Integration, Ideal for Robotic Arm and Robot Car

The Hiwonder UNO Expansion Board is a versatile, multi-functional shield designed to plug directly into an Arduino UNO main controller. It is an ideal choice for South African students, educators, and makers building robotic arms, Mecanum-wheel rovers, or sensor-rich automation projects. With onboard support for motors, servos, and wireless communication, this board simplifies complex wiring and speeds up your development.

Seamless Arduino UNO integration

This multi-functional expansion board connects directly to your Arduino UNO main controller without the need for additional wiring. It integrates motor, servo, serial, and I2C sensor ports, and comes complete with full schematics, tutorials, and source code to kickstart your learning.

Standard library and IDE support

Fully compatible with the standard Arduino development environment and libraries, this shield uses a unified communication protocol for hassle-free programming. It is available in Model A, Model B, and Model C configurations to suit different project requirements.

Advanced closed-loop control

Model B features an on-board high-performance 32-bit processor that enables precise closed-loop control and current protection. This dedicated chip ensures highly accurate management of servos and encoder motors alongside real-time voltage monitoring.

Versatile motor drive options

The board is capable of driving up to four DC motors or two encoder motors simultaneously. This makes it compatible with a wide range of mobile chassis configurations, including Mecanum-wheel, omnidirectional, 2WD, 4WD differential, and Ackerman steering systems.

Dual servo interface support

Equipped with both PWM and serial bus servo interfaces, this board is ideal for building joint-based systems such as 6DOF robotic arms. Models A and B support both servo types, while Model C is dedicated to PWM servos only.

Wireless Bluetooth control

Models A and B are compatible with the Hiwonder Bluetooth 4.0 module, enabling wireless control of your robot. You can operate your creations using a dedicated mobile app, a wireless glove, or a synchronised controller.

Multi-peripheral interface layout

The board breaks out a variety of ports, including four encoder motor channels, serial bus and PWM servo connections, and a dedicated Bluetooth port. This rich array of interfaces allows you to connect multiple sensors and peripherals to a single board.
