Joy-IT ARD Nano V3P Arduino-Compatible Nano Board ATmega328P Mini-USB

Prototyping with a full-size Arduino Uno can be cumbersome when space is tight. The Joy-IT ARD Nano V3P solves that by packing the ATmega328P microcontroller into a breadboard-friendly Nano form factor, giving you the same core functionality without the bulk.

Who is it for

This board is for makers, students, and engineers who need a compact, Arduino-compatible platform for embedded projects, wearable electronics, or quick proof-of-concept builds. It works with the Arduino IDE, so existing sketches and libraries carry over with minimal changes.

Main features

• ATmega328P microcontroller running at 16 MHz
• 14 digital I/O pins (6 with PWM output) and 8 analog inputs
• 32 KB flash memory, 2 KB SRAM, 1 KB EEPROM
• Mini-USB connector with CH340G USB-to-serial converter
• Powered via Mini-USB or VIN pin (7-12 V recommended)
• On-board LEDs for power, TX, RX, and pin 13

Specifications

• Microcontroller: ATmega328P
• Operating voltage: 5 V
• Input voltage (recommended): 7-12 V
• Input voltage (limits): 6-20 V

• Flash memory: 32 KB (2 KB used by bootloader)
• SRAM: 2 KB
• EEPROM: 1 KB
• Clock speed: 16 MHz
• USB connector: Mini-B
• USB-to-serial converter: CH340G
• Form factor: Arduino Nano V3 compatible

Tips

When uploading sketches, select “Arduino Nano” and “ATmega328P (Old Bootloader)” in the Arduino IDE to match the bootloader on this board. The CH340G driver may need to be installed on Windows before the board is recognized.
