ESP8266 Mini NodeMCU - Compact Wi-Fi Development Board
Build powerful IoT projects with the ESP8266 Mini NodeMCU - a compact, breadboard-friendly Wi-Fi microcontroller board ideal for smart home automation, sensor networks, and cloud-connected applications. Premium electronics from The Engineer Store, Bengaluru. Fast shipping, 7-day warranty on manufacturing defects, and dedicated support.
Specifications
| Microcontroller | ESP8266 (ESP-12F/E module) |
| Operating Voltage | 3.3V (5V USB input with onboard regulator) |
| Clock Speed | 80 MHz (up to 160 MHz) |
| Flash Memory | 4 MB |
| Wi-Fi | 802.11 b/g/n (2.4 GHz), built-in TCP/IP stack |
| Digital I/O Pins | 11 GPIO pins (some with PWM, I2C, SPI, UART) |
| Analog Input | 1 ADC pin (10-bit, 0-3.3V range) |
| USB Interface | Micro-USB with CH340G / CP2102 USB-to-Serial converter |
| Board Dimensions | ~34.2 mm x 25.6 mm (compact D1 Mini form factor) |
| Programming | Arduino IDE, MicroPython, NodeMCU Lua, PlatformIO |
| Type | Wi-Fi IoT Development Board |
| Origin | Original / Authentic |
| Warranty | 7-day warranty on manufacturing defects |
| Support | Email & WhatsApp 24/7 |
Key Features
- Built-in Wi-Fi: Full 802.11 b/g/n support lets you connect to any Wi-Fi network - no external modules required.
- Ultra-Compact Form Factor: The D1 Mini layout is roughly half the size of a standard NodeMCU, making it perfect for breadboards and tight enclosures.
- Plug-and-Play USB Programming: Onboard USB-to-serial chip means you simply plug in a Micro-USB cable and upload code from the Arduino IDE.
- 11 Versatile GPIO Pins: Supports digital I/O, PWM, I2C, SPI, and UART - enough for most sensor and actuator projects.
- Low Power Modes: Deep-sleep functionality draws as little as 20 uA, ideal for battery-powered IoT deployments.
- Rich Ecosystem of Shields: Compatible with a wide range of stackable D1 Mini shields - relay, OLED, motor driver, DHT sensor, battery, and more.
- Multi-Platform Support: Program in Arduino C/C++, MicroPython, Lua (NodeMCU firmware), or use PlatformIO and ESPHome.
- 3.3V Logic with 5V Tolerant USB Input: Onboard voltage regulator safely powers the board from any standard USB source.
Why Choose This?
- 100% authentic ESP8266 modules sourced from trusted, authorized suppliers
- 1-5 day shipping, 7-8 day delivery from our Bengaluru warehouse to most Indian pin codes
- Expert technical support included - get help with wiring, code, and cloud integration
- Extensive community and library support ensures you're never stuck on a project
- Unbeatable price-to-performance ratio for Wi-Fi-enabled microcontroller projects
Project Ideas
- Smart Home Automation: Control lights, fans, and appliances over Wi-Fi using Blynk, Home Assistant, or custom web dashboards.
- IoT Weather Station: Connect a DHT22 temperature/humidity sensor and BME280 barometric sensor to log data to ThingSpeak or Google Sheets.
- Wi-Fi Relay Controller: Pair with a relay shield to build a remote-controlled power switch accessible from your phone.
- MQTT Sensor Network: Deploy multiple ESP8266 Mini boards as MQTT nodes to monitor soil moisture, air quality, or motion across a building.
- OTA Firmware Updates: Use over-the-air update capability to deploy code changes remotely - no physical access needed.
- Web Server & REST API: Host a lightweight web server directly on the ESP8266 to serve sensor data or accept commands via HTTP.
- Wearable / Portable Gadgets: The tiny footprint and low-power sleep modes make it suitable for battery-powered wearable prototypes.
- Learning & Education: An excellent starting point for students learning embedded programming, networking, and IoT fundamentals.
Getting Started - Quick Guide
- Install Arduino IDE (v1.8+ or v2.x) and add the ESP8266 board package via Boards Manager (URL: http://arduino.esp8266.com/stable/package_esp
