ESP Wifi Module is a kind of wireless module revised according to ESP8266 Serial Wifi Module. The peripheral circuit needed is very simple. Only through two serial ports, TX & RX, can it realize normal work, and convenient to use with low price.ESP8266 chip integrates some key parts of power management components, TR switch, RF balun, high-power PA with peak value of 25dBm, which has 16 GPIO ports to be cited for sensor devices. It’s a good wireless connectivity solution program.
