RP Mini Dsp: common questions

What microcontroller does the RP Mini Dsp use?

The RP Mini Dsp is built around the RP2350_80QFN, from the RP2040/RP2350 family.

How big is the RP Mini Dsp PCB?

The RP Mini Dsp measures 39 × 54 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RP Mini Dsp?

67 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the RP Mini Dsp design files?

From the JackUlbrichBaker/RP_Mini_Dsp repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the RP Mini Dsp design in my own project?

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

Can I test firmware for the RP Mini Dsp 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.
