4、 Precautions for use
Relative humidity ≤ 80%
The assembly process of the entire machine requires the use of ESD protection.
When assembling the entire machine, it should be handled with care, without causing deformation or twisting of the board, and without heavy pressure.
The internal wiring of the entire set should be reasonable, and the wires should not pass directly through the PCB board, especially from the main IC, to avoid affecting the EMC performance of the entire equipment.
5、 Application scenarios
This solution has the characteristics of high integration, rich interface configuration, and good cost-effectiveness. It can be widely used in medical intelligent interaction, vehicle machine interaction, massage chair intelligent interaction, instrument display, smart home appliances, intelligent voice interaction devices, AIoT and other application scenarios.
