Rp2040-decoder: common questions

What microcontroller does the Rp2040-decoder use?

The Rp2040-decoder is built around the AMS1117-3.3, from the RP2040/RP2350 family.

How big is the Rp2040-decoder PCB?

The Rp2040-decoder measures 19.6 × 8.6 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Rp2040-decoder?

51 components, from 35 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 Rp2040-decoder design files?

From the mikesmitty/electronics-projects 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 Rp2040-decoder design in my own project?

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

Can I test firmware for the Rp2040-decoder 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.
