Batt200: Battery connector
The battery (CR1632) supplies the Realtime clock.
S200: Fastboot switch
The Fastboot switch is connected to the Fasboot-signal, which is used by different connectors
and a solder-pad of the i-PAN T10. Its function depends on the operating system. I.e. it may act
as suspend/resume switch in WEC7 or Fasboot switch for Android.
Realtime Clock
The i-PAN T10 got a Realtime-Clock which keeps time and date while the device is powered off.
It is supplied by Batt200 when disconnected from the power-supply.
Power-Fail & Voltage Supervisor
The i-PAN T10 got a circuit to detect when the input-voltage drops below a specific level.
(The level is set through resistors and can be adjusted to customer needs.)
If that happens a signal to the Trizeps powerfail GPIO (SODIMM-Pin 79) is issued and the
application software is able to shut down or store process-data. In comparison to the i-PAN XT-
Pro 10 the i-PAN T10 has got no UPS-feature (uninterruptable power supply), so that the time
between power fail and power off is greatly dependent on the external power-source.
The input voltage may be measured by ADC-input 2 of the Trizeps module (SODIMM-Pin 4).
