power - PMIC power module handling¶
New in version 1.4.
The power module allows you to read the card10’s power status
in your scripts.
Example:
import power
print(power.read_battery_voltage())
-
power.read_battery_voltage()¶ Read the battery voltage in V. Please keep in mind that battery voltage behaves exponentially when interpreting this value.
Warning
Card10 will hard-shutdown once the voltage drops below 3.4 V
New in version 1.4.
-
power.read_battery_current()¶ Read the battery-side current flow in A.
New in version 1.4.
-
power.read_chargein_voltage()¶ Read the charge voltage in V.
New in version 1.4.
-
power.read_chargein_current()¶ Read the charge current in A.
New in version 1.4.
-
power.read_system_voltage()¶ Read the system-side voltate in V.
New in version 1.4.
-
power.read_thermistor_voltage()¶ Read the thermistor voltage in V.
There is a resistor network from GND over a thermistor (10K at room temperature) over 10K to the Thermistor Bias voltage. This reads the voltage between thermistor and resistor.
