Arduino UNO R3 ATmega328P Type-C Development Board

¥7.00

Ultra-Strong 5V/2A Power Module: Capable of driving high-load peripherals like servos, toy motors, and micro-slides directly.
Integrated G|V|S Headers: Features standard 2.54mm GVS (Ground-Voltage-Signal) pin headers for every I/O, enabling “shield-free” direct connection of sensors and actuators.
Modern USB Type-C: No more orientation issues; provides a more stable data connection and higher power throughput.
Extended Analog Inputs: Includes extra A6 and A7 pins, allowing for more sensors to be integrated into a single project.
Dual Battery Support: Dedicated interface for Lithium batteries and a 6-12V DC jack for flexible mobile power solutions.
Auto Power Switching: Features a smart FDN340P + LMV358 controller that seamlessly switches between USB and external DC power to prevent interference.
On-board Diagnostic LEDs: 4 LEDs (Power, RX, TX, and D13 Pin L-LED) for instant hardware status monitoring.
MOQ: 10pcs.
Lead Time: 7~15 days.

The UNO R3 is a powerful upgrade to the classic Arduino UNO Rev3. While maintaining 100% software compatibility, this hardware revision addresses the core limitations of the original design. It replaces the legacy Type-B port with a modern USB Type-C connector and integrates a high-efficiency 5V/2A (10W) power module, allowing it to drive multiple servos, motors, and sensors directly without an external expansion shield. With added G|V|S headers and extra analog pins (A6/A7), it is the most capable and user-friendly board for STEM education, professional prototyping, and complex robotics.
