Raspi hat: common questions
What microcontroller does the Raspi hat use?
The Raspi hat is built around the DMG2305UX, from the Raspberry Pi family.
How big is the Raspi hat?
The Raspi hat measures 65.1 × 58.7 mm, has 4 copper layers and is 4.48 mm thick.
How many components are on the Raspi hat?
34 components, from 28 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 Raspi hat design files?
From the SEDS-PSU/avionics 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 Raspi hat design in my own project?
The repository has no license, so all rights stay with SEDS-PSU. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Raspi hat 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.
