Notes:
1. The -30 to +85°C temperature range is for the ST100 components and doesn't include the battery or solar panel.
2. The functional and battery charging temperature ranges are configurable parameters.
3. The power source on the battery input should be able to supply 500mA pulse current (at 3.7V) for 1.5 seconds. If the end-
application expects to have 16 packet messages, the supply should be able to provide this pulse current up to 16 times in
succession.
4. If a battery is used, the VAR/installer should verify the battery's performance at the application's lowest expected ambient
temperature before proceeding with the selected battery. User MUST set charge/discharge limits according to the battery
manufacturer's Safety Data Sheets (SDS). See command sgbattemp description for details.
5. The ST100 has the option to install a battery protection circuit. The VAR/installer will need to inform Globalstar before
ordering PCBs if this feature is desired.
6. Both the 0.75V and 50mW requirements must be met on the solar input for charging a depleted battery.
7. The maximum current the solar charger chip on the ST100 board will accept is about 100mA, regardless of solar panel
size.
8. If connecting a 5V source to the solar input, the source must be current limited to 100mA.
9. The external serial port consists of 4 GPIO pins connected to the ST100 Bluetooth processor.
10. The 24.5dBm is the conducted power going into the antenna.
