CM4IOv5: common questions
What microcontroller does the CM4IOv5 use?
The CM4IOv5 is built around the RP2040, from the RP2040/RP2350 family.
How big is the CM4IOv5 PCB?
The CM4IOv5 measures 160 × 90 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the CM4IOv5?
137 components, from 82 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 CM4IOv5 design files?
From the raybello/KICAD-PCBs 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 CM4IOv5 design in my own project?
The repository has no license, so all rights stay with raybello. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the CM4IOv5 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.
