kallisto board


The Sensry Cellular COM board complement board upgrades the Kallisto® stamp module SY020-PCB to a LPWA multi communication device for cellular services, enabling it to be used in real time tracking applications or as a standalone gadget in a rural environment. The board is designed as a mezzanine board for the Kallisto® SY020- PCB and cannot be used by itself. It contains a footprint for easy stamp module assembly. Together with Kallisto®, it combines a variety of RF standards to expand the functionality for numerous IoT use cases. The complete module will support WPA network services (Bluetooth LE) as well as LPWA network services (NB-IoT/LTE-M/3G) aside with global navigation satellite system and UHF-RFID functionality.

Together with the full software SDK/API support any tracking application can be addressed and fast realized. The data transfer over LPWA network is based on MQTT communication and grant access of all on-board sensors and functionalities.
