Electronic components and circuits are very sensitive to electrostatic discharge. Although our company
designs anti-static protection for the main interfaces on the card when designing circuit board products,
it is difficult to achieve anti-static safety protection for all components and circuits. Therefore, it is
recommended to observe anti-static safety precautions when handling any circuit board component
(including RTSO-9003U). Anti-static safety protection measures include, but are not limited to the
following:
a) The smart box should be placed in an anti-static bag during transportation and storage, and then the
board should not be taken out during installation and deployment.
b) Before touching the smart box, discharge the static electricity stored in the body: wear a discharge
grounding wrist strap.
c) Operate the smart box only within the safe area of the electrostatic discharge point.
d) Avoid moving smart boxes in carpeted areas.

The serial port level is 3.3V TTL logic level.
The mapping files in the/dev directory corresponding to UART0 and
UART1 are ttyS0, ttyTHS2
UART0 is the kernel debugging serial port by default, which is used
to output c-boot, u-boot and Linux kernel information. After Linux
kernel is started, it is used as the serial port of display control
terminal.TX2 The default serial port is set to 115200bps,8N1
The sysfs mapping Numbers of GPIO0~GPIO3 in the TX2 system
are:388,298,480,486
GPIO high level state is 3.3v.
The resulting I2C bus corresponds to the iic-0 bus in the Linux
system.
RTC-BAT pin is RTC Clock power input (+3V)
