In the first version of the BlueSCSI a blue pill microcontroller was used, which is now replaced by raspberry pi pico’s RP2040 microcontroller.

The Pico also features built-in support for SPI and I2C communication protocols, which are commonly used in SCSI to SD Card adapters.

The microcontroller features a large number of GPIO pins that can be used to interface with a variety of hardware devices, such as SD cards and SCSI interfaces. One of the benefits of using the Raspberry Pi Pico microcontroller is its flexibility. The modified firmware is open-source, which means that it can be modified and improved upon by the community. This means that the BlueSCSI v2 firmware is based on the original SCSI2SD code but has been modified to suit the specific needs of the BlueSCSI v2 adapter. The BlueSCSI v2 adapter uses a modified version of the ZuluSCSI’s SCSI2SD firmware, which has been bifurcated from the original codebase. This allows vintage computers and gaming consoles to access the SD card as if it were a SCSI device. It provides a SCSI interface that allows the adapter to emulate a SCSI device, such as a hard drive or CD-ROM. The SCSI2SD firmware is a popular open-source firmware that is used by many SCSI to SD Card adapters. The new BlueSCSI v2 is completely open source, with open hardware and open design. The new version of BlueSCSI is based on raspberry pi pico’s RP2040 microcontroller. The product is targeted to provide a reliable and cost-effective solution for vintage computer enthusiasts who are looking to upgrade their old computers. The BlueSCSI hardware can reproduce SCSI devices like hard drives, optical drives, SD cards, CD-ROMs, and many more. BlueSCSI v2 is back with a second version of their popular SCSI hard drive emulator.
