Hallpico: common questions

What microcontroller does the Hallpico use?

The Hallpico is built around the RP2040 Pro Micro, from the RP2040/RP2350 family.

How big is the Hallpico PCB?

The Hallpico measures 61 × 58.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hallpico?

16 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hallpico design files?

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

Can I use the Hallpico design in my own project?

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

Can I test firmware for the Hallpico 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.
