CrallyBoard: common questions

What microcontroller does the CrallyBoard use?

The CrallyBoard is built around the ComputeModule4-CM4, from the Raspberry Pi family.

How big is the CrallyBoard PCB?

The CrallyBoard measures 180.7 × 143.8 mm, has 2 copper layers and is 1.68 mm thick.

How many components are on the CrallyBoard?

226 components, from 112 distinct parts. The full bill of materials is listed on this page.

Where can I download the CrallyBoard design files?

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

Can I use the CrallyBoard design in my own project?

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

Can I test firmware for the CrallyBoard without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
