DTDS-622C LoRa® Modem

The DTDS-622C Modem is built based on SEMTECH® SX1262 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-622C 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. The
DTDS-622C is FCC-certified thereby simplifying the end product certification process.
