The KiCad project lives in the Cosmin-DB/SAcre repository on GitHub; these links point at the commit this page was built from.

SAcre: common questions

What microcontroller does the SAcre use?

The SAcre is built around the C193707, from the RP2040/RP2350 family.

How big is the SAcre PCB?

The SAcre measures 91.4 × 88.4 mm, has 4 copper layers and is 1.0516 mm thick.

How many components are on the SAcre?

85 components, from 53 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 SAcre design files?

From the Cosmin-DB/SAcre 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 SAcre design in my own project?

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

Can I test firmware for the SAcre 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.
