The classic Nano, modernized. We've replaced the outdated Mini-USB port with a robust USB-C connector. Powered by the ATmega328P and CH340G UART, this breadboard-friendly board is perfect for compact projects where space is a premium.
Quick Introduction: Stop hunting for that old Mini-USB cable. The Nano V3 (USB-C) updates the world's most popular compact microcontroller with a modern USB Type-C connector. It retains the same pinout and form factor as the classic Nano, making it 100% compatible with your existing breadboards and shields, but with the convenience and durability of USB-C.
Detailed Specifications
Microcontroller: ATmega328P (8-bit AVR).
Operating Voltage: 5V.
Input Voltage (VIN): 7V - 12V (Recommended) / 6V - 20V (Limit).
USB Interface: USB-C (via CH340G Chip).
Digital I/O Pins: 14 (6 provide PWM output).
Analogue Input Pins: 8.
Flash Memory: 32 KB (2 KB used by bootloader).
SRAM: 2 KB.
EEPROM: 1 KB.
Clock Speed: 16 MHz.
Dimensions: 18mm x 45mm.
Quality Advantage & Differentiation: Why choose this USB-C Nano?
Modern Connectivity: The USB-C port is reversible and far more durable than the fragile Mini-B connectors found on older Nanos, which were prone to snapping off.
Breadboard Ready: Its slim profile fits perfectly into a standard breadboard, leaving 2 rows of pins accessible on each side for easy wiring—ideal for prototyping without the bulk of an Uno.
Cost-Effective Power: Powered by the reliable CH340G USB-to-UART chip, this board offers the same performance as the original at a fraction of the cost.
Key Applications & Usage
Wearable Electronics: Small enough to be sewn into costumes or embedded in 3D printed props.
Robotics: Perfect for controlling servos and sensors in mini-sumo bots or line followers.
Sensor Nodes: Read temperature, humidity, or gas sensors and transmit data via UART or I2C.
Portable Projects: Low power consumption and small size make it ideal for battery-operated devices.
What's Included & Required
Included: 1x Nano V3 (USB-C) Board, 1x Set of Unsoldered Pin Headers.
Required: USB-A to USB-C Cable (Data capable), PC with Arduino IDE.

⚠️ CRITICAL USAGE WARNINGS:
Cable Selection: Many generic USB-C Nanos lack the "CC" (Channel Configuration) pull-down resistors required for USB-C Power Delivery. This means USB-C to USB-C cables (like MacBook chargers) often WILL NOT power the board.
Solution: Always use a standard USB-A to USB-C cable (like a standard phone charging cable plugged into a PC USB port).
Driver Installation: This board uses the CH340G chip. Windows/Mac users typically need to install the CH340 Driver manually. If the "Port" is greyed out in Arduino IDE, this is why.
Bootloader Selection: If you get an upload error, go to Tools > Processor in Arduino IDE and select "ATmega328P (Old Bootloader)". Most generic Nanos use this older firmware.
Pinout Reference:
VIN: Input for external battery (7-12V). Do not use if powered via USB.
5V: Regulated 5V output (or input if you have a regulated 5V source).
A4 (SDA) / A5 (SCL): I2C Pins.
D0 (RX) / D1 (TX): Serial Pins (Disconnected during upload).
Troubleshooting: Upload Failed?
Check USB Cable (Is it data or just charge-only?).
Try the "Old Bootloader" setting.
Verify the CH340 driver is in Device Manager (the COM port should appear).
Call to Action (CTA) Upgrade your workbench with the modern standard. Add the Nano to your cart today and prototype faster!
