Pi sfp: common questions

What microcontroller does the Pi sfp use?

The Pi sfp is built around the C5727991, from the Raspberry Pi family.

How big is the Pi sfp PCB?

The Pi sfp measures 65 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pi sfp?

48 components, from 15 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 Pi sfp design files?

From the blackbit42/pi-sfp 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 Pi sfp design in my own project?

The repository has no license, so all rights stay with blackbit42. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Pi sfp 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.
