4.4 Basic Operation of Hardware Design
1. It is recommended to offer the module with a DC stabilized power supply, a tiny power supply ripple coefficient and
the reliable ground. Please pay attention to the correct connection between the positive and negative poles of the
power supply. Otherwise, the reverse connection may cause permanent damage to the module.
2. Please ensure the supply voltage is between the recommended values. The module will be permanently damaged
if the voltage exceeds the maximum value. Please ensure the stable power supply and no frequently fluctuated
voltage.
3. When designing the power supply circuit for the module, it is recommended to reserve more than 30% of the
margin, which is beneficial to the long-term stable operation of the whole machine. The module should be far away
from the power electromagnetic, transformer, high-frequency wiring and other parts with large electromagnetic
interference.
4. The bottom of module should avoid high-frequency digital routing, high-frequency analog routing and power routing.
