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 simplex satellite 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. The ST100 board also has the option for the user to use an external serial port.
