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:

{| class="wikitable"
|-
| • 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.
