Maker Nano RP2040 is a small but powerful MCU for your project. It has the same Arduino Nano form factor, but powered by a much more powerful RP2040 MCU from Raspberry Pi. It has 14 status indicator LEDs for GPIOs, 1 piezo buzzer with mute switch, 1 programmable push button, 2 RGB LEDs (WS2812 Neopixel), 2 Maker Ports - compatible with Qwiic, STEMMA QT, Grove (via conversion cable).

We provide some examples in CircuitPython and MicroPython for your reference. Make sure the correct firmware is loaded on your Maker Nano RP2040 before you start coding with either languages.

We've created the CircuitPython .UF2 firmware for Maker Nano RP2040 with helps from the awesome folks at CircuitPython and Adafruit. It includes the libraries to work with Maker Nano RP2040's built-in features. Neopixel and simpleio libraries are embedded by default, so there's no need to add them to the lib folder of the CIRCUITPY drive manually.

Follow this guide to load the CircuitPython firmware on your Maker Nano RP2040. If you see CIRCUITPY drive appears on your computer, it means CircuitPython firmware is already loaded on board and you are good to go!

The code.py file on the CIRCUITPY drive (of any new Maker Nano RP2040) is the demo program which comes with the board. You can open this file with any code editor to view or modify it. Mu Editor is highly recommended for coding the CircuitPython. Follow Adafruit's guide to install the software.

Besides modifying the demo program, you can also open one of the CircuitPython examples here. You can copy the code and paste it in the code.py file on your CIRCUITPY drive. Save the file after making desired changes and the code will run as soon as the file is done saving.

Please wait until the file is successfully saved before resetting or unplugging your board!
