👋 Hi, I’m Yuttapichai Leelai (YuTTYL)
I’m an Embedded Systems Engineer who loves turning ideas into real hardware products — from PCB, firmware, to production.
I build small boards that go big 😎
🔥 What I Do
- Embedded System Design (ESP32, RP2350, STM32, PIC)
- IoT Devices, Wireless Communication (Thread, BLE, Wi-Fi, MQTT)
- Automotive Electronics (RGB LED drivers, LIN/CAN)
- Display & GUI (LVGL, LCD/TFT/Touch panels)
- Power electronics (DC-DC, LED drivers)
- Color science + calibration for RGB lighting
- MicroPython / C / C++ / ESP-IDF / RTOS
I love solving real problems with electronics and firmware.
