1.3. DESCRIPTION

The ST100 board is a simplex Satellite transmitter 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 or HTTP host where the user will interpret the data for further
processing. The ST100 board must be powered by a battery, or line-powered by a DC source. The ST100 Board features a
solar charging circuit that allows battery charging from an attached solar panel. The unit will not power from a solar panel
alone, without a battery. The ST100 board contains a satellite transmitter, GPS receiver, motion sensor, Bluetooth Low Energy
transceiver, solar charger, and printed circuit antennas for each of the radio subsystems. The ST100 board has u.FL connectors
on the outputs of the Bluetooth transceiver and GPS receiver / satellite transmitter, which give the user the option to use
external antennas.
