Description
The ESP-12 D1 Mini V2 Mini NodeMCU IoT Board Based on ESP8266 is a versatile and compact development board designed for fast Internet-of-Things (IoT) prototyping. Built around the ESP-8266EX WiFi-SoC, it features 4MB (32Mbit) flash memory, allowing ample space for code and data storage. This board supports Lua scripting and is fully compatible with the Arduino IDE, making it accessible for both beginners and advanced users. It includes 11 digital input/output pins, all supporting interrupt, PWM, I2C, and one-wire protocols (except D0), along with 1 analog input (3.3V max). The board operates on 3.3V logic with a built-in voltage regulator for 5V input, drawing approximately 80mA average current during WiFi operation.
Measuring 25.6×34.2mm, the D1 Mini V2 is breadboard-friendly with a micro-USB port for power and programming. It supports OTA (Over-The-Air) updates, deep sleep mode for low power consumption (down to 20µA), and is flashed with the latest firmware for immediate use. The ESP-8266EX chip provides 802.11 b/g/n WiFi connectivity, enabling seamless wireless networking for projects like smart home devices, remote sensors, or IoT gateways. For Arduino use, connect via micro-USB, install the ESP8266 board package in the IDE, and upload sketches using the “WeMos D1 Mini” board selection. This RoHS-compliant module operates from -40°C to +85°C and weighs approximately 5g.
Note: Use a stable 5V/1A power supply to avoid WiFi instability, and consider adding external antennas for extended range if needed.
