Ambient conditions of the ctrlX CORE
Notes on the temperature display
• "Temperature (CPU)" shows internal CPU temperature.
• "Temperature" shows the temperature measured by an external i2c temperature sensor.
•
The temperature sensors of “Temperature (CPU)" and "Temperature” have tolerances. Thus, the
displayed CPU temperature can be higher than the displayed temperature of the board.
