Harald Welte b76fb674e1 Add schematics + PCB layout for a simple AMR break-out board
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.

osmo-small-hardware - Various small Osmocom Hardware Projects

This repository contains a number of OSHW (open source hardware) designs. They are part of the Osmocom Open Source Mobile Communications project.

Most of the designs are done in EAGLE CAD; the schematics and board design files as well as the BOM are contained in this repository.
