Open book builder: common questions

What microcontroller does the Open book builder use?

The Open book builder is built around the SC0918, from the RP2040/RP2350 family.

How big is the Open book builder PCB?

The Open book builder measures 85 × 115 mm, has 2 copper layers and is 1 mm thick.

How many components are on the Open book builder?

29 components, from 16 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 Open book builder design files?

From the cwcorella-git/open-book-builder repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Open book builder design in my own project?

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

Can I test firmware for the Open book builder 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.
