Sol-Mk.-I: common questions

What microcontroller does the Sol-Mk.-I use?

The Sol-Mk.-I is built around the RP2350B, from the RP2040/RP2350 family.

How big is the Sol-Mk.-I PCB?

The Sol-Mk.-I measures 78.2 × 46.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Sol-Mk.-I?

72 components, from 36 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 Sol-Mk.-I design files?

From the HIIACODER/Sol-Mk.-I 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 Sol-Mk.-I design in my own project?

Yes, under the terms of its MIT license, which HIIACODER chose for the repository.

Can I test firmware for the Sol-Mk.-I 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.
