ZuluSCSI RP2040 Compact Micro SD Adapter


Emulate a SCSI hard drive using micro SD card with ZuluSCSI
ZuluSCSI RP2040 is a new member of the ZuluSCSI product family, and is powered by the Raspberry Pi Foundation's RP2040 microcontroller, a dual-core 133MHz ARM Cortex-M0+ processor. Supports synchronous and asynchronous transfers, with read speeds up to ten megabytes per second. A SCSI controller with FAST SCSI and synchronous mode is required to achieve maximum speeds.
This ZuluSCSI Compact RP2040 uses a microSD card socket, is pre-flashed with firmware, and hand-tested. All surface-mount components are factory-assembled, and the SCSI interface on the board has been tested to ensure full functionality.
ZuluSCSI is a new generation of file-based SCSI HDD & CD-ROM emulators, and represents a fusion of SCSI2SD V5, V6, and concepts from other open source SCSI emulators. Hard drive and CD-ROM drive images are stored on a standard FAT32 or exFAT-formatted SD card. The ZuluSCSI firmware looks for file names which adhere to a simple but powerful naming convention, and presents them as the drives to the SCSI host. Each image file represents a SCSI drive.
ZuluSCSI Compact RP2040 board dimensions are 90mm by 60mm
  Emulates up to 7 SCSI devices simultaneously, including CD-ROM
  Speaks both SCSI-1 and SCSI-2
  SCSI Termination is hard-enabled by default, unless you remove the thick-film resistors, and replace them with resistor packs mounted in a DIP socket
  Firmware upgrade simplicity; As easy as placing a file on the SD card.
  Highly configurable using a text-based ini file, zuluscsi.ini
  External LED pin header for attaching remote LEDs.
  Designed to be powered via SCSI termination power, when provided by the host
  Optional DB25 pin header for direct installation of an external SCSI connector, in addition to the Single-Ended 50 pin IDC connector
  Identical dimensions and mounting holes as that of SCSI2SD V5.1, V5.2, and V6, making it compatible with many existing SCSI2SD-specific mounting solutions
  74LVTH125 SCSI bus transceivers
