Module size and pin definition

The considerations hardware design

• It is recommended to use a DC regulated power supply to power the module. The ripple coefficient of the power supply should be as small as possible and the module should be reliably grounded. Please pay attention to the correct connection of the positive and negative poles of the power supply, such as the reverse connection may cause permanent damage to the module;
• Please check the power supply to ensure that the module will be permanently damaged if the maximum power supply voltage is exceeded; Please check the stability of the power supply. The voltage cannot fluctuate greatly and frequently.
• When designing the power supply circuit for the module, it is often recommended to keep more than 30% allowance, which is conducive to the long-term and stable work of the whole machine; The module should be as far away from the power supply, transformers, high-frequency wiring and other parts of large electromagnetic interference;
• High-frequency digital wiring, high-frequency analog wiring and power wiring must avoid the lower part of the module. If it is really necessary to pass through the lower part of the module, assume that the module is welded on the Top Layer, and the Top Layer of the contact part of the module is covered with copper (all copper and well grounded).Must be close to the digital part of the module and routed in the Bottom Layer.
• Assuming that the module is welded or placed in the Top Layer, it is also wrong to run wires randomly in the Bottom Layer or other layers, which will affect the stray and reception sensitivity of the module to varying degrees;
• If there are devices with large electromagnetic interference around the module, it will also greatly affect the performance of the module. According to the intensity of the interference, it is recommended to stay away from the module appropriately.
• Assuming that there are wiring (high-frequency digital, high-frequency analog, power wiring) with large electromagnetic interference around the module, it will also greatly affect the performance of the module. According to the intensity of the interference, it is recommended to keep away from the module appropriately.
• If the communication line uses 5V level, the level conversion circuit must be used.
• try to stay away from part of the physical layer is also 2.4GHz TTL protocol, such as: USB3.0;
