Burning board:

• This board is suitable for firmware burning test of modules such as Essence and 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;
• Mode indicator (blue light) and serial communication indicator (green light).

Note:

• The module supply voltage is 3.3V 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 connected to the RXD of the external MCU;
