Product Details

Nano Board R3 ATmega328P-AU with CH340 USB Chip and Mini Cable (Soldered)

The Nano Board R3 is a small, complete, and breadboard-friendly development board based on the ATmega328P-AU microcontroller. This version uses the reliable CH340G integrated circuit for USB-to-TTL serial communication, providing a cost-effective and dependable way to program the board via a USB Mini Cable (included). This board is fully compatible with the Arduino IDE and ecosystem, allowing you to run any sketches written for the standard Arduino Nano.

Despite its small size (45x18mm), the Nano R3 packs the power of the ATmega328, featuring a 16 MHz clock speed, 32 KB of Flash Memory, 2 KB of SRAM, and 1 KB of EEPROM. It offers a rich set of I/O, including 8 analog inputs and 14 digital I/O pins (6 of which can be used for PWM). Crucially, this version comes with the necessary male header pins pre-soldered, making it ready to plug directly into a breadboard or custom PCB. The manual reset switch ensures easy program restart, and the standard 0.1” spacing DIP layout is perfectly designed for prototyping.
