DTDS’s Module 622 for LoRa® communications

The DTDS’s Module 622 is built based on SEMTECH® SX1262 LoRa® based communications device controlled by RENESAS RL78 G13 family microcontroller running the LoRaWAN® stack. The module is easily interfaceable to a host controller over AT commands.

Features:

  • TCXO enabled stable clock.
  • Antenna matching network for a 50 Ohms termination is provided as a part of the module.
  • Operating Temperature range -40 deg C to +85 deg C
