Discounts available when logged in.
The WeMos D1 Mini (V2) class of ESP8266 WiFi-enabled 32 bit microcontroller development boards are compatible with Lua Script and Arduino IDE, coming with 4MB Flash Memory, and 80MHz clock speed.
ESP8266 based development boards are the perfect core for your Internet Of Things project or tiny web server.
The module is compatible with the Arduino IDE for developing and uploading programs to the Wifi module.
The header can be used to attach other WeMos D1 form factor compatible shields.
The D1 Mini is a WiFi-capable ESP8266 based development board, and it is compatible with the Arduino IDE and with NodeMCU (Lua Script).
WeMos D1 features 11 GPIO pins (input/output/PWM/I2C), thereof 1 UART (RX/TX) for serial communication, and 1 additional analog input.
Please pay attention when you connect another active periphery to the I/O pins because this is a 3.3V logic level device and higher levels on any pin can destroy it.
The max. input voltage for the analog pin is 3.2V.
Attention: This is a 3.3V logic-level device!
WEMOS D1 Mini comes with the popular CH340 USB-UART, which requires installation of the CH340 USB driver:
We recommend downloading the required WCH CH340 USB driver for your operating system from WCH official website.
