The DTDS-068C Modem is built based on SEMTECH® LLCC68 LoRa® modulation transceiver and is controlled by RENESAS RL78 G13 family microcontroller running the LoRaWAN® stack. The modem is easily interfaceable to a host controller over AT commands.
The DTDS-068C LoRa®- modem with a long range and with a low power enables a long battery life. The
modem operates in the Industry Scientific and Medical (ISM) frequency band available for free use.
