WEMOS Mini 3.0 D1 Lua WiFi IoT ESP8266 Development Board

This is the latest version of the Wemos ESP8266 mini development board V3.0 based on ESP-8266EX microcontroller. It is a multi-purpose board that is a fully functional microcontroller (SCL, SDA, SCK, MISO, MOSI, TX, RX, Reset) with the added fonctionality of connecting to a wifi network. Thus, allowing you to create a full range of IoT projects and gadgets.

The board runs off the very powerful Espresiff chip set with an on-board ceramic antenna and a dock for connecting another for better reception. The board runs at a 3.3V logic level but offers a 5V power pin. The programs are compiled using WEMOS XI expansion in Arduino.
