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, 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 BLE-based 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.
