Transceiver Module HM-TRLR-D-232-868 Introduction :
HM-TRLR-D series is a low cost, high performance transparent transceiver with operating at 433/470/868/915 MHz. It is LoRa/FSK/ GFSK/OOK modulation variety, multi-interface mode(TTL/RS232/RS485), high output power, high sensitivity, long transmission distance and most of the parameters can be set via the command. Receive and send data to automatically switch. It has a wide operating voltage and low sleep current. Users can customize the UART baud rate, output power, data rate, frequency select, modulation mode select, and other parameters. When creating wireless data transmission items that can be widely applied in the field, this is your best option.
