4.9
In 2025, a maker built an ESP32-S3–based RGB LED PCB using KiCad, four-layer layout, and NextPCB manufacturing, integrating a microphone and IMU sensors. The design uses multiple Würth Elektronik RGB LEDs, level shifters, an NCP1117 LDO, and runs MicroPython with BLE, ESP-NOW, and Edge Impulse gesture models for edge ML control. The project demonstrates a full hardware-to-software workflow for interactive lighting.
