Chapter VI Precautions
▲ Please wear electrostatic protection tools such as electrostatic bracelets when touching the motherboard (have a good grounding)：
▲ Do not operate with live assembly, wiring, etc.
▲ Please check the definition of the motherboard interface and the definition of the peripheral interface, there can be no wrong connection or reverse connection.
▲ Please use M2 flat round head screws to fix the motherboard, and do not use countersunk heads or larger screws; be careful to avoid deformation and bending of the motherboard when twisting the screws.
▲ Pay attention to the level matching of IO port, serial port, enable pin, etc.
▲ Pay attention to the power of the external screen. If the power is large, please consider external power supply.
▲ Pay attention to the overall power of the product and choose a power supply with sufficient power；
