MKLC68BA

LoRaWAN® Module

MKLC68BA is a low-lost and ultra-low power LoRaWAN node module, which integrates with Nordic Semiconductor nRF52832 (BLE) and Semtech LLCC68 (LoRa) chipsets. This module is also embedded with NRF52832 MCU to run the application code. Moreover, it is designed with industrial standards so as to be highly suitable for industrial IoT products with working temperature at -40℃ ~ 85℃.

Product Features

> Higher cost performance compared to MKL62BA
> Offers long communication range with up to 7km
> Flexible connectivity with LoRaWAN and Bluetooth protocol combined, supports the whole world LoRaWAN frequency band

> Configure with AT command
> High accuracy assured with BLE TX power default in 0 dBm and BLE RX sensitivity: -96dBm
