The self-made ESP8266 programmer supports ESP-12E/12F/12S/07S/01S for firmware programming. It can also be used as a minimum development board to access all IO ports.
The serial port chip uses CH340C and has an automatic download circuit.
Integrating the characteristics of multiple projects, the projects involved are as follows:
A 2.0MM 1*8P pin header is welded at the module contact point, which is used to connect the stamp hole of the module to facilitate flashing the firmware. The actual test results are not ideal.
The test pins welded to the module have a certain degree of elasticity and can better fix the module. It is recommended.
