Arduino Maker Nano RP2040 review

Reading Time: 2 minutes

A pair of reset pins are linked to a handy reset button on the top, where there’s also a boot button – held to attach the board as a USB drive to a computer – and a programmable button linked to GPIO pin 20.

Other connections include a micro-USB port (for power and connecting a computer) and two Qwiic / STEMMA QT ‘maker ports’ which also work with Grove modules using the two supplied adapter cables.

Lights and sound

On either side of the micro-USB port are two RGB NeoPixel LEDs. Since both are linked to GPIO 11, they can’t be controlled separately, but some cool colour-changing effects can be achieved. In addition, 14 of the digital pins have tiny blue status LEDs that may well prove useful when troubleshooting I/O connections for circuits.

Primitive audio is also provided in the form of a piezo buzzer that can be muted with a slide switch. It can be programmed to play beepy tunes by sending numerical note values.

Talking of coding, the Maker Nano RP2040 comes with CircuitPython firmware pre-installed, including a mini demo that shows off the lights and sound. More code examples are found in the GitHub repo: Alternatively, you can flash MicroPython firmware or program in C/C++ (natively or via the Arduino IDE). Like Pico, it’s very flexible.
