D1 Mini Pro NodeMCU WiFi LUA ESP8266 ESP-12 WeMos Microcontroller w/ Antenna US
D1 Mini Pro Microcontroller WeMos, NodeMCU and Arduino compatible LUA ESP8266 ESP-12 Wifi Development Board with External 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 on-board microUSB connection. With only 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.

Same dimensions as D1 Mini, but lighter
Compatible with Arduino, Nodemcu and MicroPython
This D1 Mini comes with 3 different types of header connectors to support various configurations:
Female
Male
Female/Male (long female)
In most cases, the female headers are the best choice as they allow you to install the various shields that are available.
NOTE: There is a "Zero Ohm" jumper connecting the circuitry to the internal ceramic antenna. In order to use the external antenna, you must desolder this resistor, rotate it 90 degrees to connect the circuitry to the external antenna, and resolder it. Or simply remove it, and solder a jumper wire in its place. Please see the Envistia Mall support page for this product for more details on this procedure.
