1.3. DESCRIPTION
The ST150M is a transmit-only Satellite IoT module designed to send small packets of user defined data to a network of low
earth orbiting (LEO) satellites using the Globalstar commercial IoT network. The received data is then forwarded to a user
defined network interface that may be in the form of an FTP host, HTTPS host or HTTP host where the user will interpret the
data for further processing.
The ST150M is designed to be integrated into an integrator's custom carrier board design. The ST150M can operate 100%
autonomously once configured or can be controlled via external interfaces/AT commands, or can be modified with custom
firmware leveraging the onboard Nordic 52840 as the applications processor.
The ST150M can be configured via the Globalstar Mobile App, through the BLE configuration service, or through a physical or
BLEbased UART.
The ST150M includes value-added software modules that can be configured for tracking applications based on GPS and/or
accelerometer movement detection, input-based count, accumulate, state, and transition events, interval or time-of-day events,
and even Smart One Sensor Service data.
The ST150M consists of the Nordic NRF52840, External Flash, GPS, accelerometer, ASIC, and internal power controls. It
does not have an onboard patch antenna. The Nordic and ASIC are shielded for modular certification. The ST150M has gold
"fingers" around the perimeter of the PCB so that it can be SMT-installed onto a carrier board or another custom PCB.
