DESCRIPTION
At the heart of the Dev Kit is the Globalstar STX3 module. The STX3 module 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 STX3 is a surface mount module and it is mounted on the bottom side of the Transmitter board just under the
Taoglas antenna. The STX3 is electrically connected to the Nordic Bluetooth processor through the two headers that
attach the two PCBs of the Dev Kit together. Also, the Main PCB provides power, an RF connection to the transmit
antenna, and communications with a host processor which will control the operation of the STX3.
