WeMos D1 Nodemcu ESP8266Mod-12f WiFi Module Arduino
This board is the famous D1 board with the ESP8266 Wifi module, perfect for IoT applications.
The ESP8266Mod is the big brother of the D1 Mini, whose main core is the ESP8266-12F module. Compared to the D1 Mini, this board offers more pins and thusconnection options to directly connect any modules to the wifi board without the need for additional microcontrollers. The basis of this board is the ESP8266-12F module, which is equipped with the ESP8266EX chip. This means that you are prepared for all possible applications.
D1 Board Nodemcu ESP8266Mod-12f uses the same shape and size of conventional boards, so you can use different types of shields with this board. The D1 development board is pin compatible with most shields. It has 10 GPIOs, all PWM, with I2C port and 1 analog input. The module is compatible with Arduino IDE and has a micro USB port.
Technical details of the D1 Development Board
11 digital input / starting pins, all pins have supported Interrupt / PwM / I2C / Einadig (except D0)
1 analog input (3.3 V Max. Input)
A micro USB connection
A power connection, 7-12V electricity input.
Compatible with Nodemcu, Microphyton and Arduino
