Description
Arduino compatible module based onESP8266 WiFichip. It has the ability to connect to the wireless network and 11 digital inputs/outputs, 10 PWM channels, 1 analog input and popular communication interfaces. This version works with 3.3V and has a microUSB connector for programming.
ESP8266 controllerprovides WiFi connectivity, thanks to the built-in controller the system can be programmed through Arduino IDE environment usingmicroUSB cable(sold separately). The board also works with NodeMCU.
The kit includesgoldpinconnectors for self-soldering.
