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](https://osmocom.org/) 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.
