The PCB layout has changed for an improvement in WiFi radio performance.

This ESP8266 code burner firmware downloader is suitable for firmware burning test of modules such as ESP-12S/12F/12E/07S/07.
All IO ports have been exported and can be used as a minimum system development board or a small batch burning fixture.
The board supports firmware one-click download function and adds programming.

Notice:
The module supply voltage is 5V DC and the current is 500mA or more.
Wi-Fi module IO maximum output current is 12mA.
Wi-Fi module NRST pin is active low; EN enable pin is active high.
The Wi-Fi module enters the upgrade mode:
GPIO0 is at a low level, then the module is reset and powered on;
the Wi-Fi module enters the normal working mode: GPIO0 is at a high level, and the module is reset and powered.
The RXD of the Wi-Fi module is connected to the TXD of the external MCU, and the TXD of the Wi-Fi module is conne
