Transceiver 433MHz TTL interface.

Transceiver 433MHz RS232 interface.

Note: straight antenna included

433MHz transceiver module, 4.5 to 5 volt operation. FSK, 2 way half-duplex, data rate 300 - 19200bps, 0.1" pin spacing, SMA antenna connector. Serial RS232 interface. Range up to 1Km depending on conditions.
HM-TR series transparent data link module is dedicated for applications that needs data transmission. It features high data rate. The communication protocol is self controlled and completely transparent to user interface. The module can be embedded to your current design so that communication can be set up easily.
