Notes:

1. As the operating temperature provided in the specifications is a result of testing performed in VIA’s

chamber, a number of variables can influence this result. Please note that the working temperature may

vary depending on the actual situation and environment. It is highly suggested to execute a solid testing

program and take all the variables into consideration when building the system. Please ensure that the

system runs well under the operating temperature in terms of application.

2. Please note that the lifespan of the onboard eMMC memory chip may vary depending on the amount of

access. More frequent and larger data access on the eMMC memory makes its lifespan shorter. Therefore,

it is highly recommended to use a replaceable external storage (e.g., Micro SD card) for large data access.
