Libreboard broken: common questions
What microcontroller does the Libreboard broken use?
The Libreboard broken is built around the ComputeModule5-CM5, from the Raspberry Pi family.
How big is the Libreboard broken PCB?
The Libreboard broken measures 125 × 125 mm, has 6 copper layers and is 1.5584 mm thick.
How many components are on the Libreboard broken?
164 components, from 74 distinct parts. The full bill of materials is listed on this page.
Where can I download the Libreboard broken design files?
From the 256foundation/libreboard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Libreboard broken design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which 256foundation chose for the repository.
Can I test firmware for the Libreboard broken 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.
