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.

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.
Compared to the D1 Mini, the D1 Mini Pro offers:
- Flash: 16M bytes (128M bits) in the D1 Mini Pro vs 4M bytes (32M bit) in the D1 Mini
- USB-TO-UART IC: CP2104 vs CH340G
- Antenna: Built-in ceramic antenna or an external antenna vs a PCB antenna in the D1 Mini
- Weight (without pins): 2.5g vs 3.9g
- Thickness: 3.6mm vs 6.7mm
Package Includes:
- 1x D1 Mini Pro ESP8266 ESP-12 WiFi Development Board NodeMCU Lua
- Two each Female, Male, and Female/Male (long female) connectors
- External WiFi Antenna
