The dietSCSI is a SCSI disk emulator, designed to be low-cost while remaining highly functional.
- SMT-first design, optimized for modern low-cost assembly services
- Target price of ~$10 each in small quantities from JLCPCB, fully assembled
- This implies that the retail price for a fully-assembled board could be $20 with a 100% markup
- Can be hand-assembled using only parts that are readily available from DigiKey (Except for the STM32 microcontroller, but those aren't readily available anywhere at the moment)
- Integrated DB25 and 50-pin IDC connectors on one board. A single PCB design covers multiple use cases, ideal for easy switching between multiple computers
- This also means that you can use the dietSCSI itself as a DB-25 to 50-pin SCSI adapter in a pinch
- On-board termination (jumper-selectable)
- Design files for 3D printed cases are available in variants for both portable usage and 3.5" hard disk replacement
- 0.1" headers for external activity LEDs
- Can be powered via SCSI termination power or from an external source
- Designed to run firmware based on the open source BlueSCSI firmware
- Default firmware has both USB image passthrough and USB firmware update support built in (see the usage page for details).
