Apple 68k FujiNet: common questions

What microcontroller does the Apple 68k FujiNet use?

The Apple 68k FujiNet is built around the C529589, from the RP2040/RP2350 family.

How big is the Apple 68k FujiNet PCB?

The Apple 68k FujiNet measures 80.8 × 55.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Apple 68k FujiNet?

22 components, from 20 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 Apple 68k FujiNet design files?

From the FujiNetWIFI/fujinet-hardware 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 Apple 68k FujiNet design in my own project?

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

Can I test firmware for the Apple 68k FujiNet without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
