D1 Mini Pro NodeMCU WiFi LUA ESP8266 ESP-12 WeMos Microcontroller w/ Antenna

The D1 Mini Pro is an Arduino compatible microcontroller based on the WiFi-SoC ESP8266EX and is made for fast Internet-of-Things (IoT) prototyping. It offers the convenience of a micro-USB connection for both power and data (running at 3.3V), and despite its size has built-in WiFi with an external antenna for greater transmission distances, and 16MB of flash memory. It can be programmed with Arduino or LUA, and supports both serial and OTA programming. The development board is based on the WiFi-SoC ESP8266EX and is made for fast Internet-of-Things (IoT) prototyping. It is flashed with the NodeMCU firmware and can be set up and programmed right away with the onboard micro-USB connection. With only a few lines of code, the NodeMCU Dev Kit is connected to your local network and ready to be controlled by other network members like computers and smartphones.
