Squishbox: common questions

What microcontroller does the Squishbox use?

The Squishbox is built around the Raspberry_Pi_2_3, from the Raspberry Pi family.

How big is the Squishbox PCB?

The Squishbox measures 53 × 34 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Squishbox?

31 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 Squishbox design files?

From the sinitsinmike/squishbox 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 Squishbox design in my own project?

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

Can I test firmware for the Squishbox 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.
