SDR TRX from Radioberry

VSWR - Module ==============================================

For the radioberry this module gives the possibility for getting information about the vswr during transmit.

The module contains the possibility to measure the REF and FORWARD power.

Using a low speed i2c module makes it possible to read the data using the raspberry pi.
