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.
