2021-11-17Add schematics + PCB layout for a simple AMR break-out boardHarald Welte2-0/+3055
AMR (Audio Modem Riser) is a standard for pluggable boards with audio codecs to connect to the AC97 interface of mainboards dating to the late-90ies / early 2000s. The idea of this break-out boards is to be able to interface such a modem riser card with a microcontroller or FPGA, basically using them as a digital interface to analog phone lines for softmodem development as part of osmocom retronetworking.
