3. Look at the power consumption

Some products need high power consumption, long transmission distance; and some products need low power consumption, low power consumption; so be sure to ask when buying wireless modules power consumption, receiving current, output current and other specific parameters.

4. Look at the antenna

Wireless network module is divided into PCB antenna and an external antenna, external antenna is divided into several kinds, communication distance, that day the line must choose the right antenna system can be better directional and extend the communication distance.

5. Look at the price
