DIYables D1 Mini NodeMCU Lua WiFi Development Board ESP8266 ESP-12F CH340 for Arduino IDE, Presoldered
Click to zoom
Quick Overview
This DIYables D1 Mini NodeMCU development board is built around the ESP8266 ESP-12F chip, delivering reliable WiFi connectivity for IoT automation, wireless control, and smart home applications. Equipped with a CH340 USB-to-serial chip, the board connects easily to Arduino IDE for stable programming and code upload. Header pins come presoldered, so the board is ready to plug into a breadboard or connect to wires straight out of the box.
The compact D1 Mini form factor packs 11 digital I/O pins supporting PWM, I2C, and interrupt functionality, plus 1 analog input, into a small footprint ideal for space-constrained projects. Onboard 4 MB flash provides ample storage for firmware and data. Compatible with Arduino IDE (C/C++) and Lua scripting via NodeMCU firmware, this board suits a wide range of development styles. This 2-pack includes two complete presoldered boards, offering great value for multi-node networks or keeping a spare on hand.
Ideal for DIY electronics, smart home devices, wireless sensor nodes, STEM education, and hobbyist IoT projects. Works with the extensive library of ESP8266-compatible sensors, displays, and modules available across the Arduino and NodeMCU ecosystems.
