Dog dev: common questions

What microcontroller does the Dog dev use?

The Dog dev is built around the Raspberry_Pi_4B_Aligned_Mount_3.2mm_6mmPad, from the Raspberry Pi family.

How big is the Dog dev PCB?

The Dog dev measures 71 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Dog dev?

13 components, from 10 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 Dog dev design files?

From the PT233/dog_dev 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 Dog dev design in my own project?

The repository has no license, so all rights stay with PT233. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Dog dev 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.
