Assembley Precautions
K-3568
主板组装和使用时请注意以下关键事项:
Please note the following key points when using
the K-3568 mainboard:
1.
本产品相对湿度:
10%
~
90
%,无凝露。
Relative humidity of this product: 10% to 90%, no
condensation.
2.
本产品工作温度:
0°~70°
。
The working temperature of this product: 0°~70°.
3.
本产品存储温度:
-40°~70°
。
This storage temperature of this product: -40 ° ~ 70 °.
4.
整机装配和运输过程中需做防静电处理。
Anti-static treatment is required during assembly
and transportation of this product.
5.
本板接口连接线缆不可过长,否则可能会影响信号质量。
The board interface connection
cable must not be too long. Otherwise, the signal quality may be affected.
6.
整机装配时严禁使板子受到扭曲或重压而变形。
Never allow the board to be distorted or
heavily stressed during assembly.
7.
严禁裸板与其他外设之间发生短路。
Do not short circuit between mainboard and other
peripherals.
8.
外接
LVDS
或
eDP
液晶屏时,注意驱屏电压和电流是否符合要求,且注意屏线插座
1
脚
方向。
When connecting to external LVDS or eDP LCD screen, pay attention to whether the
screen voltage and current meet the requirements, and pay attention to the screen
connector pin-1 direction.
9.
外接
LVDS
或
eDP
液晶屏时,注意背光电压和电流是否符合要求。
液晶屏背光功率在
20W
以上则建议使用单独的电源板进行背光供电
。
When connecting to external LVDS or
eDP LCD screen, pay attention to whether the backlight voltage and current meet the
requirements.
10.

电平
和电流是否符合要求。
使用主板接插件上的电源管脚给外设供电时,常规电源脚电流
严禁超过
100mA
、
USB
电源脚电流严禁超过
500mA
。串口连接外设时还需要电平匹配
(
3.3V TTL
电平、
RS-232
电平和
RS-485
电平)。
When connecting to peripherals using USB,
GPIO, Serial, I2C, SPI, HDMI, etc., pay attention to whether the IO voltage level and current
of the peripheral meet the requirements. When using the power pin on these connectors to
