DJI RoboMaster TT Expansion Kit (GL)

The RoboMaster TT Expansion Kit (GL) unlocks advanced DIY flight and programming possibilities by upgrading TELLO EDU to RoboMaster TT. It includes an open-source controller, a dot-matrix display with distance sensing, and an extension board, supporting Arduino, MicroPython, Scratch, and SDK-based development.

This kit is designed for learners, educators, and developers who want to explore advanced drone programming and hardware expansion. By adding this kit, you can upgrade a TELLO EDU into a RoboMaster TT and gain access to open-source hardware that supports both online and offline programming.

At the core of the kit is the open-source controller powered by an ESP32 dual-core MCU, offering strong performance, dual-band Wi-Fi, Bluetooth connectivity, and broad programming compatibility. The included dot-matrix display and TOF distance-sensing module enable interactive visual output and obstacle or distance detection, making it ideal for STEM education and creative projects.

The extension board provides flexible DIY connections and supports third-party sensors, allowing users to expand functionality even further. With support for Arduino, MicroPython, Scratch, and DJI SDK, this kit is perfect for hands-on learning, robotics education, and experimentation with autonomous flight logic.
