+RF Sub-1GHz modules
+
+## Dependencies :
+This repository relies on Techno-Innov's base elec repository which holds the domotab library.
+It can be cloned from here http://git.techno-innov.fr/?p=elec/base
+ git clone git://git.techno-innov.fr/elec/base
+
+
+## Description :
+The RF Sub-1GHz modules have been created for the domotab project as a communication module
+ for the DTPlug.
+The module would have allowed communication with most of the appliances using Sub-1GHz RF
+ communication (For example 433MHz and 868MHZ for europe or 315 and 915 MHz for US).
+Only the 868MHz version has been tested yet (in 868MHz and 915MHz configurations).
