1. Descriptions of RF Data Link Transceiver Module HM-TRLR-SW:

HM-TRLR-SW series is a low cost, high performance transparent RF data link module transceiver module with operating at 433/470/868/915MHz. It is LoRa/FSK/ GFSK/OOK modulation variety. It features small size, 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. Use generic UART interface. It is easy to realize the wireless data transmission with only providing the UART data. It is flexible for the users to set the UART baud rate, output power, data rate, frequency select, modulation mode select etc parameters. It is your ideal choice for designing wireless data transmission products which can be widely used on wireless data transmission field.
