WeMOS D1 Mini NodeMCU ESP8266-12F ESP-12 CH340 for Arduino Microcontroller

WeMOS D1 Mini ESP8266-12F WiFi Module for Arduino and ESP8266

A compact WiFi module based on the ESP8266 chip, fully compatible with the popular Wemos D1 Mini standard. At its core is an integrated ESP8266-12F module equipped with 4 MB of Flash memory. Communication with a computer is provided by a built-in CH340 USB-UART converter. The board offers a rich set of pins, including 11 GPIO pins (10 of which support PWM), an ADC analog input, and common interfaces: UART, I2C, SPI, 1-Wire. Power and programming are via a microUSB connector.

This module is an excellent alternative to original solutions, using a proven processor and memory in a ready-made ESP-12F module. It is an ideal choice for IoT projects requiring reliable wireless communication using the ESP8266 platform. Importantly, the microcontroller can be programmed easily directly from the popular Arduino IDE.
