Mai pico nano io: common questions

What microcontroller does the Mai pico nano io use?

The Mai pico nano io is built around the RP2040-Zero, from the RP2040/RP2350 family.

How big is the Mai pico nano io PCB?

The Mai pico nano io measures 50 × 35 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mai pico nano io?

21 components, from 9 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Mai pico nano io design files?

From the Isoheptane/mai-pico-nano repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Mai pico nano io design in my own project?

Yes, under the terms of its MIT license, which Isoheptane chose for the repository.

Can I test firmware for the Mai pico nano io without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
