Description
The module is compatible with Arduino-based on wi-fi ESP8266. It has the ability to connect to a wireless network and 11 digital inputs/outputs, 10 channels of PWM, 1 analog input, as well as popular communication interfaces. This version works with a voltage of 3.3 V and has a microUSB connector for programming.
The ESP8266 controller provides communication with a wi-fi network, thanks to the integrated controller, the system can be programmed via the Arduino IDE through the microUSB cable (sold separately). Board is also working with NodeMCU.
