Tinyu Zhao
Software Engineer at M5Stack
Summary
🤩
RockstarTinyu Zhao is a software engineer with seven years of hands-on experience specializing in C++, Python, embedded systems, and IoT development. They have contributed to widely used ESP32 Arduino core and M5Stack repositories, adding board-specific pin mappings and improving example code for devices like M5StickC and M5AtomS3. Tinyu’s work shows practical expertise across firmware, I2C/peripheral integration, display and touch interfaces, and cellular/LoRaWAN modules, enabling hardware to work reliably across variants. Comfortable bridging low-level hardware details and user-facing examples, they strengthen developer experience by making complex peripherals easy to use. An engineer who prefers solving real-world embedded problems, Tinyu often surfaces subtle hardware-software assumptions in example code to improve product usability.
