Description: 1. Microcontroller: ESP-12 D1 Mini V2 is a compact Wi-Fi microcontroller board based on the Espressif Systems ESP-12F chip, which includes a Xtensa dual-core 32-bit CPU and integrated Wi-Fi & Flash memory. 2. Size & Design: With dimensions of approximately 55.5mm x 24mm, it is smaller than an Arduino Uno but offers more capabilities. Its minimalist design makes it ideal for IoT projects where size and weight are crucial factors. 3. Connectivity: The ESP-12 D1 Mini V2 comes with built-in Wi-Fi (802.11 b/g/n) connectivity, making it simple to connect the board to various wireless networks for remote control, data logging, and real-time monitoring applications. 4. Flash Memory: The board comes with onboard flash memory (up to 512KB), which can store your code and data persistently, eliminating the need for an external SD card or USB stick. 5. GPIOs & I/O Pins: It offers several general-purpose input/output (GPIO) pins that support a wide range of sensor and actuator interfaces such a
