RRFExtRP2040Board: common questions

What microcontroller does the RRFExtRP2040Board use?

The RRFExtRP2040Board is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the RRFExtRP2040Board PCB?

The RRFExtRP2040Board measures 100 × 95 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RRFExtRP2040Board?

86 components, from 40 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 RRFExtRP2040Board design files?

From the nyarurato/RRFExtRP2040Board 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 RRFExtRP2040Board design in my own project?

The repository has no license, so all rights stay with nyarurato. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the RRFExtRP2040Board 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.
