Wireless Transparent Modules



Dual-mode transceiver operating in the 434 MHz ISM band with extremely compact dimensions. The module operates as an independent device that can be controlled through external control lines.
The module has been developed to comply with the Radio Equipment Directive (RED) 2014/53/EU.
Compliant with REACH and RoHS directives.

Two different operating modes are possible:
- Normal mode (default): The TRX module operates as a dual channel (433.42- 434.42 MHz) transceiver in OOK. Through the external pins, the user can control the operation mode (Tx, Rx, stand-by) and the channel frequency. Supports data rates up to 4800 baud.
- Extended Mode (User-programmable): through a predefined sequence of serial commands sent on input pins, the user can enter configuration mode and then customize the module. It is possible to set the output power, the frequency of the channel (selectable for each channel between 433.42, 433.92 and 434.42 MHz), the modulation (ASK, OOK), baud rate, etc.
