Cyberboard: common questions

What microcontroller does the Cyberboard use?

The Cyberboard is built around the STM32WB55RGVX, from the STM32 family.

How big is the Cyberboard PCB?

The Cyberboard measures 51 × 21 mm, has 4 copper layers and is 1.5842 mm thick.

How many components are on the Cyberboard?

64 components, from 36 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 Cyberboard design files?

From the notaroomba/cyberboard 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 Cyberboard design in my own project?

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

Can I test firmware for the Cyberboard without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
