STD-601 434 MHz
Preliminary
The STD-601 434 MHz is a miniature 434 MHz band transceiver designed for industrial remote control applications. This module conforms
to the EN 300 220 standard.
The STD-601 434MHz has a simple serial interface and allows own communication protocol to be used. The RF Power, Data rate and Channel
can be set through the use of dedicated serial commands.
Features
