BitDogLab 5.4: common questions

What microcontroller does the BitDogLab 5.4 use?

The BitDogLab 5.4 is built around the DMG2305UX-13, from the Raspberry Pi family.

How big is the BitDogLab 5.4 PCB?

The BitDogLab 5.4 measures 87.9 × 123.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BitDogLab 5.4?

56 components, from 44 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 BitDogLab 5.4 design files?

From the BitDogLab/BitDogLab 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 BitDogLab 5.4 design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which BitDogLab chose for the repository.

Can I test firmware for the BitDogLab 5.4 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.
