Rascsi 2p4: common questions
What microcontroller does the Rascsi 2p4 use?
The Rascsi 2p4 is built around the RASPBERRY_PI_2_3, from the Raspberry Pi family.
How big is the Rascsi 2p4 PCB?
The Rascsi 2p4 measures 65 × 56 mm and is 1.6 mm thick.
How many components are on the Rascsi 2p4?
86 components, from 23 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 Rascsi 2p4 design files?
From the PiSCSI/piscsi-hw repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Rascsi 2p4 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 Rascsi 2p4 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.
