The Universal Serial Interface for the Amstrad CPC (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 running games from Usb Stick, MIDI, RS232 and accessing online BBS.
