R3 Nano Atmega328P Pin Soldered | Unsoldered (Compatible with Arduino)

The R3 Nano Atmega328P is a compact, Arduino-compatible development board based on the ATmega328P microcontroller. It's commonly used for projects that require small-sized, low-power consumption boards.

  • TTL Level Serial Transceiver Ports (RX/TX):

    • One pair of serial communication pins for receiving (RX) and transmitting (TX) data at TTL (Transistor-Transistor Logic) level. These are used for serial communication with a PC or other devices.

  • Microcontroller (MCU):

    • Atmel ATmega328P-AU: A highly popular and efficient microcontroller based on the AVR architecture, which powers the board.

  • Pre-installed Bootloader:

    • The board comes with a pre-loaded bootloader (often Arduino's Optiboot), allowing you to upload programs via USB without the need for an external programmer.

  • USB Download and Power Support:

    • You can program the board and power it through a USB connection. This supports USB power input, typically 5V.

  • External Power Supply Support (5V to 12V DC):

    • The Nano can also be powered externally through the Vin pin (7V to 12V) or a regulated 5V through the 5V pin.

  • 9V Battery Power Support:

    • The board supports a 9V battery power option, typically via the Vin pin.

  • ISP Download Support:

    • You can program the board using In-System Programming (ISP) via the ICSP header. This is useful for burning the bootloader or for programming the board without USB.

  • Automatic Reset During Program Download:

    • The Nano board will automatically reset when you start downloading a new program, eliminating the need for manual intervention.

  • Status LEDs:

    • Blue LED (Power OK): Indicates that the board is powered correctly.
    • Green LED (TX): Lights up when data is being transmitted.
    • Red LED (RX): Lights up when data is being received.
    • Orange LED (L): Connected to digital pin 13 and useful for quick status indicators or diagnostics.

  • +5V to AREF Jumper:

    • A jumper allows selecting between 5V or an external reference voltage for the Analog Reference (AREF) pin, enabling more control over analog input resolution.

  • Auto-Sensing/Switching Power Input:

    • The board can auto-switch between power sources (USB or external power) depending on which one is available.

  • ICSP Header for Direct Program Download:

    • A 6-pin ICSP header allows for direct programming using an external programmer, handy for bootloader burning or bypassing the USB interface.

  • Standard 0.1” Spacing DIP (Breadboard-Friendly):

    • The pins are arranged in a standard 0.1" spacing, making the board compatible with most breadboards for easy prototyping.

  • Manual Reset Switch:

    • A reset button is available on the board for manually resetting the microcontroller.
