Possibly the smallest esp8266 IoT development board (8 x gpio)

Overview

If you have any suggestions, please feel free to put them forward!

In this development version, there are a total of 8 gpio pins and 2 pairs of power pins. The current mainstream typec interface is used. You are not afraid of reverse plugging. The board comes with a ch340 serial port chip, so there is no need to use additional ttl programming. device, and the size is only 22.6x26.6mm! ! It can be said that although a sparrow is small, it has all the internal organs! This work is very suitable for use in smart homes. The general development board is bulky and difficult to plug into sockets and other places, but this work can be easily plugged in. (In order to reduce space, all silk screens have been removed. Just follow the pcb file when welding)
