Description: 1. Microcontroller: Arduino Nano R3 is a compact microcontroller board based on the ATmega328P chip, making it suitable for various IoT projects requiring low power consumption and minimal size. 2. Compatibility: This development board is compatible with the Arduino IDE and most shields designed for Arduino boards due to its standard Arduino R3 pinout layout. 3. Size: With dimensions of 45mm x 19mm, Nano R3 is smaller than traditional Arduino boards like Uno or Mega, making it ideal for space-constrained projects and wearable tech applications. 4. Input/Output Pins: It features 26 digital input/output pins (of which seven can be used as PWM outputs), six analog inputs, a 16MHz quartz crystal, USB connection, an ICSP header, and reset button. 5. Flash Memory and SRAM: Arduino Nano R3 offers 32KB of flash memory for storing code and 2.5 KB of SRAM for data storage, ensuring sufficient capacity for most IoT projects. 6. Power Supply: The board can be powered via the USB connection o
