The D1 Mini NodeMCU is a small development board based on the powerful ESP8266-12F WLAN module, equipped with a Micro-USB/USB TYPE-C interface and CH340G driver for easy connection and programming. Due to its compact size, this NodeMCU is particularly popular among developers. It features built-in Wi-Fi functionality and supports Arduino IDE programming, enabling developers to rapidly prototype smart devices. Equipped with up to 11 GPIO pins and support for I2C, SPI and UART communication, the D1 Mini is ideal for applications such as IoT projects, smart home and remote monitoring, greatly expanding its application scenarios.
For easy and comfortable programming a CH340 chip is on board.
This compact development board can be used for various applications and projects due to its light weight and design.
For example, it can measure air pressure, temperature and humidity with many of our sensors via its own web server via WLAN connection.
