5-Pack D1 Mini NodeMCU Board WiFi LUA ESP8266 ESP-12 WeMos Microcontroller 5X

Open-source, Interactive, Programmable, Low cost, Simple, Smart, WI-FI enabled FOR Arduino-like hardware IO Advanced API for hardware IO, which can dramatically reduce the redundant work for configuring and manipulating hardware. Code just like Arduino, but interactively in Lua script. Nodejs style network API Event-driven API for network applications, which facilitates developers writing code running on a 5mm*5mmsized MCU in Nodejs style. Greatly speed up your IOT application developing process.   Specs: D1 Mini WiFi board based on ESP8266                            Compatible with Arduino and NodeMcu                         This is new version V2                             Version 2 Use BRT (Bias Resistor Transistor) thus making it easier going into flash mode Stabler operation than Old Version 1.0 board                       11 digital input/output pins, all pins have interrupt/PWM/I2C/one-wire supported (except D0)                       1 analog input (3.3V max input)
