WIFI ESP8266-PRO module is based on widely explored esp8266 System on Chip from Expressif.
WIFI ESP8266-PRO it is light version of NodeMCU board. WIFI ESP8266-PRO dont have USB-TTL serial converter. For programming from USB, need connecting to USB-TTL converter, or any other serial programming module.
It is similar if compare Arduino Nano and Arduino Pro-Mini.
It combined features of WIFI accesspoint and station + microcontroller and uses simple LUA based programming language, also microPython.
- Arduin0-like hardware IO. And can programming in Arduin0 IDE
- Event-driven API for network applicaitons
- 10 GPIOs D0-D10, PWM functionality, IIC and SPI communicaiton, 1-Wire and ADC A0 etc. all in one board
- Wifi networking (can be uses as access point and/or station, host a webserver), connect to internet to fetch or upload data.
- For developing can use install to breadboard.
