This project is a custom ESP32-S3 development board designed using KiCad. It integrates native USB-C programming, efficient power regulation, and GPIO breakout, eliminating the need for an external USB-to-UART converter. The design follows Espressif reference guidelines and is suitable for IoT and embedded applications.

Pro Micro/Elite-Pi compatible RP2040 board with USB-C, 8MB flash and up to 25 GPIOs

Without using a USB-C PD controller chip, handling communication over the USB cable, USB-C standard allows to get 5V up to 3A through a hardware availability detection. Here I show a design developed on KiCad and made through JLCPCB, powering from a USB-PD source and providing 5V and 3.3 (through a step-down converter) up to 3A.
