XianWill emcu D2 (new concept wemos)

Overview

This project is in the process of being patched by smt. We will continue to follow up and welcome to discuss together.
If this project is successful, more de-modularized products will be launched
Oh, this board is not only smaller than the ordinary D1, but also has a lithium battery charging protection circuit, ipex socket , IIC screen direct socket, Type-c, etc., and also adds useless ESD. The original parts on the back (ch340c, ESD) do not need to be soldered, and the back is flat for placing the battery , which is suitable for WiFi killer and other occasions.
- - Short contact point 1 Short circuit activates Deep Sleep
  - Short contact point 2 Short-circuit to measure battery voltage
IIC is XianWill's package, which is 2.54mm 2*2. Commonly used in 12864oled.
Typec adds a resistor and can be used for master-slave identification of CtoC power supply.
F1 is a self-restoring fuse
Thanks to Tingqiuyu for supplementing and revising Essence based on the Espressif Manual!
I will spare no effort to answer any questions you may have, thank you for your message.
