From the project

SCSIknife Pocket - The SCSI jump drive

SCSIknife Pocket is a ZuluSCSI™ PICO OSHW derivative, compatible with the ZuluSCSI™ PICO firmware.

SCSIknife Pocket is an extremely compact SCSI disk drive emulator designed to be plugged externally to a computer or SCSI enabled device.

SCSIknife Pocket require 5.0VDC ± 0.5V which can be supplied by the SCSI termination or USB-C. SCSIknife Pocket is available in DB25, HD50 or Centronics50 version.

SCSIknifePocket: common questions

What microcontroller does the SCSIknifePocket use?

The SCSIknifePocket is built around the RP2040, from the RP2040/RP2350 family.

How many components are on the SCSIknifePocket?

90 components, from 39 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 SCSIknifePocket design files?

From the Siliconinsid/SCSIknifePocket repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.

Can I use the SCSIknifePocket design in my own project?

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

Can I test firmware for the SCSIknifePocket 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.
