MKL68BA

LoRaWAN Module

MKL68BA is a standard LoRaWAN node module designed and manufactured by MOKO technology Ltd. The module integrates with the world-leading Nordic Semiconductor nRF52832 (BLE) and Semtech LLCC68 (LoRa) chipsets, providing ultra-low power consumption with excellent cost performance using the LoRa radio link and local BLE connections.

• Higher cost performance compared to MKL62BA
• More suitable for LoRaWAN communication scenarios in close proximity, such as smart water meters
