RPI5-CFE-Hat: common questions
What microcontroller does the RPI5-CFE-Hat use?
The RPI5-CFE-Hat is built around the CH32V003F4P6, from the STM32 family.
How big is the RPI5-CFE-Hat?
The RPI5-CFE-Hat measures 65 × 56 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the RPI5-CFE-Hat?
44 components, from 27 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 RPI5-CFE-Hat design files?
From the will127534/RPI5-CFE-Hat 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 RPI5-CFE-Hat design in my own project?
