  • High Performance: The transmit power up to 33 dBm @868/930MHz; 11.23dBm @ 2.4-2.5GHz
  • Wireless Connectivity: SPI interface, supports Sub-GHz global LoRa&LoRaWAN frequency plan and 4GHz
  • Small Size: 17*12*2.6mm @24Pins SMT
  • Low Power Consumption: 35uA sleep current;Sub-GHz: [email protected]/3.3V; 2.4G:[email protected]/3.3V
  • RF Interface: With IPEX4 @1.5mm
  • FCC, CE, Certified

 

The Wio-LR1121 and Wio-E5 are both perfect choices for designing LoRa devices. Their main differences lie in whether you have a host MCU.

If you need a single MCU to complete your design, then the Wio-E5 is an excellent choice.
