RaspberryPi-Uno: common questions

What microcontroller does the RaspberryPi-Uno use?

The RaspberryPi-Uno is built around the RP2040, from the RP2040/RP2350 family.

How big is the RaspberryPi-Uno PCB?

The RaspberryPi-Uno measures 68.6 × 53.3 mm, has 2 copper layers and is 1.64592 mm thick.

How many components are on the RaspberryPi-Uno?

62 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the RaspberryPi-Uno design files?

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

Can I use the RaspberryPi-Uno design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the RaspberryPi-Uno 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.
