This is WiFi serial transceiver module, based on ESP8266 SoC which has integrated TCP/IP protocol stack.
It optimizes the filter circuit and reduces power consumption.It is an upgraded and improved version of ESP-07 module.
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, and controlling home appliances by the mobile phone.
Solder it to the ESP-07 adapter board and then it can be plugged directly into a breadboard or PCB experiment board.
Compatible with pin pitch and pinout of ESP-07
Working frequency: 2400 – 2484 MHz
Working voltage: 3.0 – 3.6VDC
Working current: 200mA(MAX)
Serial port baud rate: 115200 (default), can be modified to other values by AT command
Serial communication format: 8N1
