Arduino Nano V3.0 CH340 Development Board (Upgraded Type-C)

When you have finished prototyping your code on an Arduino Uno and are ready to build the final, permanent version of your project, the Arduino Nano V3.0 is your next step.

It packs the exact same 16MHz ATmega328P processor as the Uno, meaning 100% of your code and libraries will work without any modifications. The major difference is the form factor. The Nano is designed with standard 0.1-inch pitch headers pointing downwards, allowing it to snap directly into a standard breadboard or be soldered flat onto a zero-PCB or a custom motherboard.

This specific model is the upgraded version featuring a Type-C USB connector. It eliminates the need to keep obsolete Mini-B cables on your workbench. It also uses the robust CH340G USB-to-Serial chip, ensuring reliable uploads every time you hit "Flash" in the Arduino IDE. It is the ultimate microcontroller for space-constrained projects like mini-sumo robots, wearable electronics, or compact sensor nodes.

Key Features

• Microcontroller: ATmega328P (8-bit AVR architecture).
• Operating Voltage: 5V Logic Native (Perfect for easy interfacing with standard 5V sensors).
• Input Voltage: 7-12V via the VIN pin, or 5V directly via the Type-C USB port.
• Clock Speed: 16 MHz Crystal Oscillator.
• Flash Memory: 32 KB (of which 2 KB is used by the bootloader).
• SRAM / EEPROM: 2 KB SRAM, 1 KB EEPROM.
• Digital I/O: 14 Pins (6 provide 8-bit PWM output for motor control).
• Analog Inputs: 8 Pins (A0-A7) with 10-bit resolution (Two more than the Uno!).
• USB Interface: Modern Type-C port with CH340G Serial Converter.

Pinout

1. VIN: External Unregulated Power Input (7-12V).
2. 5V / 3V3: Regulated power output pins for driving sensors.
3. GND: Common Ground (2 pins available).
4. TX1 / RX0: Hardware Serial pins for communication (Bluetooth, GPS, etc.).
5. D2 - D13: Digital I/O (D3, D5, D6, D9, D10, D11 support PWM).
6. A0 - A7: Analog Input pins for reading variable voltage sensors.
7. RST: Reset Pin (Pull LOW to restart the microcontroller).
8. AREF: Analog Reference voltage for the ADC.
