Piscsi: common questions
What microcontroller does the Piscsi use?
The Piscsi is built around the C50982, from the Raspberry Pi family.
How big is the Piscsi PCB?
The Piscsi measures 65 × 56 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Piscsi?
81 components, from 19 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 Piscsi design files?
From the PiSCSI/piscsi-hw 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 Piscsi design in my own project?
Yes, under the terms of its BSD-3-Clause license, which PiSCSI chose for the repository.
Can I test firmware for the Piscsi 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.
