DeltaRho: common questions

What microcontroller does the DeltaRho use?

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

How big is the DeltaRho PCB?

The DeltaRho measures 68 × 75 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the DeltaRho?

114 components, from 50 distinct parts. The full bill of materials is listed on this page.

Where can I download the DeltaRho design files?

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

Can I use the DeltaRho design in my own project?

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

Can I test firmware for the DeltaRho 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.
