DRF7020D20 is one of most mature modules based on ADF7020 RFIC. It also adopts high efficient EDAC technology which makes communication link more robust. DRF7020D13, DRF7020D20 and DRF7020D27 modules use the same chip and data format so they can communicate with default settings. The different output powers of DRF7020Dxx series modules provide flexibility in communication range and BOM cost.
Both of DRF4432D20I and DRF4432D20 are 20dBm data radio modem modules based on RFIC SI4432 from Silicon labs. DRF4432D20 is GFSK module which utilizes innovative coding technology EDAC to improve the reliability of wireless communication link. DRF4432D20I is a type of FSK module with netID and nodeID which can be used to reduce the data collision in the same area and same frequency band. The working frequency range of DRF4432D20I is divided into 40 channels with fixed 1MHz channel space. Because of different software algorithm, DRF4432D20 and DRF4432D20I are imcompatible in communication. DRF4432D20I modules have three interfaces (TTL/RS232/RS485) for selection.
