Environmental Safety Instruction
Avoid the dusty, humidity and temperature extremes. Do not place the product in
any area where it may become wet.
0 to 60 centigrade is the suitable temperature. (The figure comes from the request
of the main chipset)
Generally speaking, dramatic changes in temperature may lead to contact
malfunction and crackles due to constant thermal expansion and contraction from
the welding spots’ that connect components and PCB. Computer should go
through an adaptive phase before it boots when it is moved from a cold
environment to a warmer one to avoid condensation phenomenon. These water
drops attached on PCB or the surface of the components can bring about
phenomena as minor as computer instability resulted from corrosion and oxidation
from components and PCB or as major as short circuit that can burn the
components. Suggest starting the computer until the temperature goes up.
The increasing temperature of the capacitor may decrease the life of computer.
Using the close case may decrease the life of other device because the higher
temperature in the inner of the case.
Attention to the heat sink when you over-clocking. The higher temperature may
decrease the life of the device and burned the capacitor.

1* GPIO header
1* SMBUS header
* Note: 1. Many PCs now include XHCI USB controllers which allow for the support of USB 3.0 and higher USB
speeds. This inclusion of XHCI controllers has lessened the need for EHCI USB controllers within platforms.
However, legacy operating systems (OS) may not natively recognize XHCI controllers. You might need to pre-
install XHCI driver while desiring to install a non-xHCI OS (ex.Windows* 7) on Intel platforms which do not include
EHCI controllers. Please contact your representative for more details. 2. Braswell SOC will support memory speed
at 1600 MHz and 1066 MHz only. If 1333 MHz DIMM is installed, it will run at 1066 MHz. It is not validated while
installing 1066MHz DIMM with this SOC.
