value is exceeded, the module will be permanently damaged.
 Please check the stability of power source, the voltage cannot fluctuate too much.
 Please make sure anti static measure are taken when installing and using, high frequency devices have electrostatic
susceptibility.
 Please ensure the humidity is within limited range, some parts are sensitive to humidity.
 Please avoid using modules under too high or too low temperature.
9.3 BER(Bit Error Rate) is high
 There are co-channel signal interference nearby, please be away from interference sources or modify frequency and
channel to avoid interference.
 Poor power supply may cause messy code. Make sure that the power supply is reliable.

The extension line and feeder quality are poor or too long, so the bit error rate is high.
10 Production guidance
This type is DIP module, when the welder welds the module, he must be welding according to the anti-static regulation.
This product is allergic to static, randomly welding the module will have the chance of damaging it permanently.

12 Antenna recommendation
The antenna is an important role in the communication process. A good antenna can largely improve the
communication system. Therefore, we recommend some antennas for wireless modules with excellent performance and
reasonable price.
