CM5IO: common questions

What microcontroller does the CM5IO use?

The CM5IO is built around the ComputeModule5-CM5, from the Raspberry Pi family.

How big is the CM5IO PCB?

The CM5IO measures 160 × 90 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the CM5IO?

63 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the CM5IO design files?

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

Can I use the CM5IO design in my own project?

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

Can I test firmware for the CM5IO 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.
