Uno Rev3 Board, USB-C, Arduino Uno R3 Compatible

Overview

The Uno Rev3 development board is a fully Arduino Uno R3 compatible platform built around the ATmega328P. Because it matches the official board's pinout and behaviour, every existing Uno sketch, shield, library and tutorial applies directly — there is nothing new to learn.

It provides 14 digital I/O pins (D0–D13) and 6 analogue inputs (A0–A5), ready for sensors, LEDs, buzzers, buttons, relays and motor drivers. Power can come from USB or an external 7–12 V DC supply, and the board offers both 3.3 V and 5 V outputs so mixed-voltage peripherals can share the same project.

This version uses a modern USB Type-C connector for programming and power.

Key Features

• Arduino Uno R3 compatible — Works with existing Uno projects, shields, libraries and community resources
• ATmega328P microcontroller — The proven 8-bit AVR at 16 MHz, reliable and very well documented
• Versatile I/O — 14 digital pins (D0–D13) and 6 analogue inputs (A0–A5)
• Multiple power options — USB bus power, or an external 7–12 V DC supply for standalone use
• Dual voltage rails — 3.3 V and 5 V outputs for mixed-voltage peripherals
• USB Type-C — Reversible connector for programming and power
