Transceivers

An IQRF transceiver (TR) is a tiny intelligent electronic board with complete circuitry needed for implementation of wireless RF connectivity. It is a basic communication component of the IQRF platform, used also in all IQRF gateways, routers etc.

Data controlled (DCTR)

There is no difference between TR and DCTR (Data Controlled) transceiver versions from IQRF OS v4.02D. All TRs support both OS as well as DPA approaches.
