PiDaughterBoard: common questions

What microcontroller does the PiDaughterBoard use?

The PiDaughterBoard is built around the Raspberry PI Header, from the Raspberry Pi family.

How big is the PiDaughterBoard PCB?

The PiDaughterBoard measures 191.5 × 116 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PiDaughterBoard?

165 components, from 43 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 PiDaughterBoard design files?

From the mekatrol/electronics 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 PiDaughterBoard design in my own project?

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

Can I test firmware for the PiDaughterBoard 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.
