Magnetic Encoder Board: common questions

What microcontroller does the Magnetic Encoder Board use?

The Magnetic Encoder Board is built around the RP2350A, from the RP2040/RP2350 family.

How big is the Magnetic Encoder Board?

The Magnetic Encoder Board measures 40 × 40 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Magnetic Encoder Board?

72 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Magnetic Encoder Board design files?

From the ROAR-QUTRC/perseus-v3 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Magnetic Encoder Board design in my own project?

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

Can I test firmware for the Magnetic Encoder Board 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.
