Kevin-CE21/ESP32-S3-Multimedia-LED-PCB
A 2-layer, heart-shaped carrier PCB that combines an ESP32-S3, 28 PWM-dimmed LEDs, a TFT display with microSD, and I2S audio on one USB-C-powered board. Designed from scratch in KiCad, from schematic through layout.
Kevin-CE21/PCB-Hotplate01
This project is a custom designed PCB hotplate for reflow soldering, built around an Arduino Nano. The board reads real time temperature through an analog LMT85 sensor and displays live readings on an I2C OLED screen…
