The original LOLIN Wemos D1 Mini (V3.1.0) is the last update of the successful series of D1 Mini ESP8266EX WiFi enabled 32 bit Microcontroller Development Boards. It is compatible with Arduino IDE, MicroPython, and NodeMCU. LOLIN Wemos D1 Mini V3.1.0 comes with the powerful 80/160MHz Microcontroller from Espressif, featuring 4MB Flash Memory and 2.4GHz Wifi compatibility.
ESP8266 based development boards are the perfect core for your Internet Of Things project, or tiny web server.
This very popular 2.4GHz WiFi module (802.11b/g/n) is almost 10 times faster than an Arduino Uno, and comes with plenty of memory. After installing the board file, the Arduino IDE can be used to develop and upload programs to the Wifi module. The header can be used to attach other WeMos D1 form factor compatible shields.
LOLIN Wemos D1 Mini features 11 GPIO pins (all expect D0 can be input/output/PWM/I2C) and 1 analog input (max. 3.2V).
Attention: This is a 3.3V logic level device! Connecting it to 5V logic components might require level converter/shifter.
