CybdoKeebs hub: common questions
What microcontroller does the CybdoKeebs hub use?
The CybdoKeebs hub is built around the RP2350_60QFN, from the RP2040/RP2350 family.
How big is the CybdoKeebs hub PCB?
The CybdoKeebs hub measures 290 × 24 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the CybdoKeebs hub?
72 components, from 22 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 CybdoKeebs hub design files?
From the Cybdo/CybdoKeebs 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 CybdoKeebs hub design in my own project?
The repository has no license, so all rights stay with Cybdo. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the CybdoKeebs hub 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.
