DMC’s custom evaluation board combines the Quectel KG100S module, GPS, and multiple sensors, along with storage and interface expansions, into a single compact platform. The firmware leverages standard Amazon Sidewalk examples for sub-GHz connectivity, augmented by DMC’s custom drivers for sensor acquisition, GPS data parsing, and data compression.
Provisioning each device securely registers it on the Sidewalk network, a process fully automated in the Docker-based build system.
By buffering sensor readings locally and transmitting only essential, compressed data, the solution optimizes bandwidth usage while delivering extended battery life
A custom Amazon AWS-based application was also developed to ingest and visualize the data received from the sensors.
Overall, this evaluation system demonstrates the practicality of low-power, long-range IoT devices using Amazon Sidewalk.
