[Verified in kind] Cheap and easy-to-use ESP32 spring pin programming and debugging rack

This is the new ESP32 burning rack following the cheap and good ESP8266 burning rack!

Same cheap, same easy to use, but this time the gap of the ESP32 is smaller, and soldering the spring pins requires a little skill; you need to use heat-resistant tape to tape the non-soldering holes to prevent solder from pouring into the vias!

 The ESP32 package of this project is copied to YAKE's programmer project at https://oshwhub.com/YAKE/esp_-ce-shi-ban_ver2

This project uses a new UMH3N component , which is 2 resistors plus 2 NPN transistors.

Just completed the automatic download function.

When I drew this picture, I wasn't sure whether it would be useful or not, but the actual test turned out to be really good! The size is not much larger than a 0603 resistor . It is a real space-saving thing! ! !

The disadvantage is that it is small:) Maybe the newbie is not very good at welding.

My self-made version 1.0 does not have a power light. I originally thought it would be fine without it, but after testing, I found that without this light, I can only rely on the computer to identify the sound emitted by the hardware as a sign of whether it is normal. .

So I added it anyway!

Not much else to say, friends who like it should hurry up and imitate it!
