Rp2350-boards: common questions

What microcontroller does the Rp2350-boards use?

The Rp2350-boards is built around the RP2350A-QFN60, from the RP2040/RP2350 family.

How big is the Rp2350-boards PCB?

The Rp2350-boards measures 21 × 66.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rp2350-boards?

62 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rp2350-boards design files?

From the abzman/rp2350-boards repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Rp2350-boards design in my own project?

Yes, under the terms of its Unlicense license, which abzman chose for the repository.

Can I test firmware for the Rp2350-boards 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.
