NodeMCU V2 ESP8266 ESP-12E WiFi Development Board – Breadboard Friendly IoT Module with CP2102 in Pakistan

Overview

The NodeMCU V2 is an open-source Lua-based firmware and development kit that helps you prototype your IoT products within a few lines of code. Unlike the wider “V3” versions, the V2 (Amica) is specifically designed to be slim, leaving one row of holes free on either side of a standard breadboard. It is powered by the ESP-12E module, giving you full WiFi connectivity to connect your sensors to the cloud, Home Assistant, or a local web server.

Key Features 

• Breadboard Optimized: Its narrow footprint is the #1 reason engineers prefer the V2 over the V3.

• Stable USB Connectivity: Built-in CP2102 USB-to-UART bridge is faster and more reliable than cheaper CH340 clones.

• Plug & Play: Includes an onboard 3.3V regulator—just plug in a Micro-USB cable and start programming.

• Multilingual: Supports Arduino IDE (C++), MicroPython, and the original Lua firmware.

• Integrated WiFi: 802.11 b/g/n support with integrated PCB antenna for excellent signal range.
