The wireless module is a static-sensitive device. Pay attention to the static electricity protection when using it. Especially in the dry winter, try not to remove the device on the touch module to avoid unnecessary damage.

The wireless module recommends using a DC power supply with a small ripple, and the operating voltage is recommended to operate at 3.3V.

The grounding of the module should be stable and reliable, and the ground wire should be as close as possible to the power supply. If you use a switching power supply, you must strengthen the retraction to avoid the ripple and spikes of the switching power supply affecting the operating characteristics of the module.

The module uses a PCB antenna. This antenna is easily affected by external circuits. When using it, please do not leave the line or place the device under and around the antenna. If possible, it is best to hollow out. The 2.4G frequency is relatively high, and various materials have certain influences. The general plastic has little effect. If there is a metal object, it will have a significant impact. In this case, it is recommended to use an SMA feeder to connect the SMA antenna.
