USB to ESP8266 module
Overview
USB to ESP8266 module can ESP8266 wireless module through the serial port to connect the PC, easy to debug ESP8266 WIFI module.
Features
Using CH340 chip, stable performance, good compatibility, Windows system, all the basic support;
Switch board with 1000uF solid capacitors to ensure that the current supply, not because of power problems so that WIFI module crash without response;
Board Function Description:
ESP8266 wireless WIFI module and USB interface in the same direction for docking, (Note: ESP8266 WIFI module to be purchased separately), the module can be inserted into the computer can use the serial debugging assistant software test ESP8266 module.
