From the 1541 Ultimate Website:
Specification_1541U Features:
- Full emulation of a real Commodore 1541 diskdrive.
- Uses .D64 files stored on SD card
- Supports .G64 files as well (Read only)
- Configurable ID
- Configurable ROM (1541/1541C/1541II or custom)
- RAMBOard memory expansion (16K)
- Secondary 'IEC-drive' for direct access to FAT filesystem.
- Can be used in stand alone mode to mount disks into the emulated 1541.
- FAT/FAT32 support, with sub-directories and long filenames
- Supports SD V1.1 cards as well as SD V2.0 in High Capacity mode (SDHC)
- C64 cartridge emulation:
- Final Cartridge III
- Action Replay
- Retro Replay
- Super Snapshot
- Turbo Assembler w/ Codenet
- Commodore 1750/1764 REU
- REU Compatible
- Size selectable from 128K up to 16 MB
- Can be combined with Retro Replay and SuperSnapshot compatible roms
- Integrated RR-net compatible Ethernet port
- Available as an option on a new order only!
- No flimsy stackup board, but fully integrated.
- Flexible freezer menu
- select, mount, create D64 images, browse disk images
- create new directories, delete files
- Ultra fast DMA load of single file programs (directly from SD / from a .D64 with automount and from a .T64 file)
- Configuration screen, with resident settings
- Load of last disk on power up
- 'Stand-alone mode'
- keeps the cartridge port free
- powered through Mini-USB connector

Future
As of this writing the 1541U-II is under development. It will feature
- the board itself is about 30% smaller than the 1541U;
- it has a MicroSD connector, instead of a full-size SD;
- it has a real-time-clock function, for correct file time and date;
- it has a larger FPGA, which enables the implementation of more features;
- it has a USB Host port, which can be used to connect USB-sticks;
- it is targeted to have a suitable case for the device.
