esp8266 burning folder

Previously, I modeled the esp8266 burning socket on Taobao and made one. The effect was good and the price was much lower than the finished product on Taobao, but there were still many shortcomings:

1. It’s too troublesome. To make a burning socket, you need to buy a test ring and bend it yourself. Although it reduces the cost, it also wastes a lot of unnecessary effort;
2. For the disassembled module, because the edge of the module is tinned, the module will not stay obediently in the burning socket, and may accidentally bounce off;
3. For a board that has been soldered and does not have a serial port chip on it, the process of burning it again will become extremely cumbersome. You have to either fly the wires or remove it for burning, which is a nightmare for people like me who don’t have a heat gun;

Therefore, following the design of @prism and @duck , we came up with this burning folder:

1. First of all, the programming clip has its own download circuit, so programming can be achieved by placing the module on it without flying wires;
2. Even if the module has been soldered, it can still be programmed using this programming clip without flying wires or removing it;
3. Dual USB design. People who are familiar with me know that I have always used Type-C. However, in order to be compatible with some people who still use MicroUSB, it also gives my board wider compatibility, so my boards are generally Dual USB design, even if it does not exist, two versions will be released;
4. The price is cheap and low. Compared with the expensive burning clips on Taobao, this one is still very good.
