E43-900T13S3 User manualCopyright ©2012–2019，Chengdu Ebyte Electronic Technology Co., Ltd. 18In the configuration PC, the module address and frequency channel are displayed in decimal mode, and the range ofparameters is:Module Address：0 ～ 65535Frequency Channel：0 ～ 2559. Hardware Design It is recommended to use DC stabilized power supply to supply power to the module. The power supply ripplecoefficient is as small as possible, and the module needs to be reliably grounded. Please pay attention to the correct connection of the positive and negative poles of the power supply. If the reverseconnection is connected, the module may be permanently damaged. Please check the power supply to ensure that between the recommended supply voltage, if exceeding the maximum,the module will be permanently damaged. Please check the stability of the power supply, the voltage can not be significantly frequent. When designing the power supply circuit for the module, it is often recommended to reserve more than 30% of themargin, and the whole machine is beneficial for long-term stable operation. The module should be as far away as possible from the power supply, transformers, high-frequency wiring and otherparts with large electromagnetic interference. High-frequency digital traces, high-frequency analog traces, and power traces must be avoided under the module. Ifit is necessary to pass through the module, assume that the module is soldered to the Top Layer, and the copper is
