1. The specificati n is subject t change with ut pri r n tice.
2. As the perating temperature pr vided in the specificati ns is a result f the test perf rmed in VIA’s
chamber, a number f variables can influence this result. Please n te that the w rking temperature
may vary depending n the actual situati n and envir nment. It is highly suggested t execute a
s lid testing and take all the variables int c nsiderati n when building the system. Please ensure
that the system runs well under the perating temperature in terms f applicati n.
3. Please n te that the lifespan f the nb ard eMMC mem ry chip may vary depending n the
am unt f access. M re frequent and larger data access n eMMC mem ry makes its lifespan
sh rter. Theref re, it is highly rec mmended t use a replaceable external st rage (e.g., Micr SD
card) f r large data access.
