Keyestudio NANO PLUS Development Board Compatible with Arduino NANO

The Keyestudio NANO PLUS is a compact development board fully compatible with the Arduino Nano, powered by the ATMEGA328P-AU microcontroller. It is an excellent choice for students, educators, and makers looking to build space-saving robotics projects. With its versatile pinout and easy programming, it integrates seamlessly into any learning or prototyping environment.

ATmega328P-AU microcontroller core

At the heart of the board is the ATMEGA328P-AU processor, matching the official Arduino Nano's performance. It utilises the CH340G USB-to-serial chip for reliable communication and programming.

Versatile digital and analog I/O

The board features 14 digital input and output pins (D0-D13) and 8 analog inputs (A0-A7) to connect a wide array of sensors and actuators. Six of the digital pins can be configured for PWM output to control motors or dim LEDs.

Flexible power and programming

You can power and programme the board using a type-CUS cable, a mini USB port, or via the VIN and GND pins supporting DC 7-12V. An onboard ICSP interface is also available specifically for programming the Atmega328P-Au chip.

Memory and clock speed

Operating at a clock speed of 16 MHz, the board includes 32 KB of flash memory, with 2 KB reserved for the bootloader. It also features 2 KB of SRAM and 1 KB of EEPROM for data storage.

Built-in LED and reset button

For quick debugging and user interaction, the board includes a built-in LED mapped to digital pin D13. A physical reset button is also integrated to easily restart your running code.

Safe operating parameters

The development board operates at a standard 5V voltage, with a recommended input voltage range of DC 7-12V. Each I/O pin supports a maximum DC current of 40 mA, ensuring safe integration with low-power components.
