Super mini ESP32 PICO D4 development board

Overview

A little thinner than a thumb, PICO D4 is difficult to weld. If your welding skills are not good enough, be careful to bring an independent button and an LED. Integrated automatic download circuit. All usable IOs are led out. Due to the pursuit of small size, the breadboard will be a little tight. When welding the pin header, it can be Plug it into the breadboard first and then solder it so that the pins have a slight outward slope for easy insertion later.
