USB CH340 to TTL (ESP8266) Development Board

USB to ESP-07 module has CH340G USB to TTL driver IC onboard. This makes it easy to use your computer to power and use this device.
ESP-07 is WiFi serial transceiver module, based on ESP8266 SoC.The SOC has Integrated TCP/IP protocol stack.It is TTL serial communication interface and its parameters can be set by AT command. It is widely used in networking, smart home project when it is connected to the wifi router. It can be used for remote monitoring of home appliances, bedroom temperature and humidity, controlling home appliances and smart car by the mobile phone.
