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.
