DRAGONEYE G0 with 1.3'' Rotary Encoder Display & STM32 MCU
M0
Accelerate your embedded GUI development
The DRAGONEYETM -G0 is a pre-developed hardware and software development platform that enables you to bring compact, high-quality graphical interfaces to life with minimal effort Built around the STM32G0 Arm® Cortex®-M0 microcontroller, it delivers an efficient solution for cost-sensitive embedded applications.
Combining a 1.3″ TFT display, a rotary encoder with push button, and full TouchGFX support, DRAGONEYETM allows you to prototype, evaluate, and deploy user interfaces quickly - cutting both development time and overall BOM cost.
- STM32G0 Arm® Cortex®-M0
- 1.3" TFT with 240x240 pixels
- Rotary encoder with integrated pushbutton*
- 8MB Flash memory
- UART interface
- RGB LED light ring
- Supports TouchGFX UI designer software
*NEW version of DRAGONEYE-G0 available in July 2026 will feature brushless rotary encoder with haptic feedback and integrated CTP.
