ESP8266NodeMCU

Overview

This project has been going on for a long time. I couldn't find the MicroUSB data cable when using NodeMCU. At that time, I decided to draw a Flag for Type C NodeMCU, but due to various reasons (lazy), I never drew it. Keep cooing. Then today I worked for a few hours and came up with this project.

First of all, the size used in the appearance is 1000*1900mil, and it is as compact as possible under the premise that the resistance and capacitance are 0603 packages. Similarly, there are two versions, CP2102 and CH340. The chip used in the CH340 version is CH340K, which is much smaller than the commonly used CH340C/G.

Then an ESD diode is added to the USB to prevent static electricity from damaging the computer's USB.

ESP8266 is compatible with all models of ESP12 and ESP07, and modules can be replaced freely.

All pins of ESP8266 are lead out.

Why can't my microcontroller count 1HZ square waves accurately?
I am using C8051F120. I used two methods to measure the 1HZ square wave. I feel that the first time I measured, I only recorded 1-10 falling edges (I used a 12864 screen display and could see the reco
