Full Compatibility with Arduino UNO
The Arduino UNO uses a unified communication protocol and supports the Arduino development environment along with related libraries. The expansion board connects seamlessly to the UNO microcontroller without the need for additional wiring. Available in Model A, Model B, and Model C.
High-Performance 32-Bit CPU
The on-board high-performance 32-bit chip enables closed-loop control and current protection, ensuring precise control of servos, encoder motors, and voltage monitoring. This feature is available exclusively in Model B.
Support DC/ Encoder Motor
The expansion board can drive 4-channel DC motors and 2-channel encoder motors, meeting the interface requirements of most vehicle models on the market, including 2WD, 4WD differential, Mecanum-wheel, omnidirectional wheel, steering, and Ackerman drive systems.
Supports PWM and Serial Bus Servos
The expansion board features both PWM and serial bus servo interfaces, making it easy to implement 6DOF robotic arms and other joint-based robotic systems. Models A and B support both PWM and serial bus servos, while Model C supports only PWM servos.
Supports Bluetooth Communication
The expansion board is compatible with the Hiwonder Bluetooth 4.0 module, allowing you to control the robot via the app, wireless glove, or synchronized controller. This feature is supported only by Model A and Model B.
Multiple Peripheral Interfaces
Includes 4-channel encoder motor port, serial bus servo port, bluetooth port, PWM servo port, and more, enabling flexible control of multiple peripherals.
