4.8.6. Temperature sensor
There is internal temperature sensor in the device. Sensor is controlling the display
brightness according to temperature sense information thus protecting the device from
overheating and decreasing the risk of display image sticking with static images.
4.9. Mass storage
A Micro SD-card can be attached to Pro Display to provide mass-storage capabilities for
large amounts of data. This is especially good for transferring music, video clips, maps
etc. that is to say, large files that may not be appropriate for storage in a module’s
internal memories, but in external Micro SD/Micro SDHC memory cards, due to their
size.
Pro Display supports UHS-I SDR104 mode. Micro SD cards with UHS-I speed class and
basic speed classes 2 to 10 and UHS-I are supported. Application and environment
