Robo Uno Shield

The Cytron Robo Uno Shield is a multifunctional robotics add-on board for the Arduino Uno and Uno-compatible boards. It simplifies motor and servo control, sensor integration and power management by reducing the need for external components or complex wiring.

Designed for educational and prototyping use, it includes dedicated ports for Grove and Qwiic/STEMMA QT, as well as built-in support for 2x DC motors and 4x servos. It also features automatic power selection, LiPo battery charging with protection, and direct compatibility with both Arduino IDE and mBlock programming platforms.

As always with Cytron’s hardware – that’s not all – it’s packed with lots of other handy features such as IO indication LEDs, motor quick test buttons and more. Check out the video below and the features list to learn more!
