The '''U'''niversal '''S'''erial '''I'''nterface '''f'''or '''A'''mstrad '''C'''PC (USIfAC), currently in version 2 (Styled USIfAC II), is a modern serial interface based around a PIC microcontroller designed and built by [[ikonsgr]] from the CPCWIKI Forums.
The only chip on the board is the 18F47Q10 PIC. The PIC software is written in Great Cow Basic and has been released by [[ikonsgr]].

The board allows for TTL serial output and connection to a USB Stick as well as a ESP8266 WIFI module.
The board has been used for many purposes including:
- Run games/programs from a usb stick or PC Hard Drive (through ESP8266 WiFi module or UART serial cable). Save is also supported, as well as full access to ASCII files too
- Full read/write access of DSK images of both AMSODS and PARADOS formats
- Very fast loading speeds of up to ~30kb/sec (more than 6-7 times faster ,than a usual speed of a gotek/floppy disk drive)
- Access up to Four DSK images and choose them "on the fly", to support all multi-image Games
- Load SNA snapshot files
- MIDI, RS232 and accessing online BBS
