Accessories

1)Antenna Antenna is very important for RF communication, its performance will affect the communication directly. Module needs antenna in 50ohm. Common antenna has rubber straight/ elbow/ foldable rod and sucker antenna and etc. Users can order accordingly. To ensure module in the best performance, we suggest to use the our antenna

Appendix:
The module is possible to be equipped with a standard DEMO board for customer to debug the program and test distance. It shows as below:

Our company is engaged in researching, developing, producing and selling IOT(internet of things) products. We devoted ourselves on providing good RF modules, walkie talkie modules and integrated digital sensor modules. Meanwhile, ODM and OEM projects are welcomed. With more than 10 years experience of product design in RF and sensors, we have earned a good reputation among our customers.

  Delivery time   1.Sample order:1-3 days 2.Normal order:3-7 days 3.OEM Order:7-15 days 4.ODM Project: development time is around 1 months after all details confirmed.   Warrenty   1.100% test low than 0.05% defective rate 2.Free technical support   MOQ   1.Sample Order: 2pcs/a pair 2.OEM Order: More Than 1000pcs   Aftersale Service   1.Give replacements if there is quality issue of the part in future order 2.Evaluate the customs risk and choose safest shipping company during different period 3.Fllow status from time to time till the goods arrive client's hand 4.NiceRF warranty does not apply to products purchased through third-party verdors       a) Why module can not communicate properly?   1) Check if the band, channel, rate, NET ID has set to the same; 2) Check if there is power connection error; 3) Check if the module is enabled (CS high); 4) Check if the antenna connection is not correct; 5) Check if the module is damaged.   b) Why transmission distance is not far as it should be?   1) Power supply ripple is too large; 2) The antenna types do not match, or not properly installed; 3) The surrounding environment is harsh, strong interference sources; 4) Surrounding co-channel interference;   c) Why receiving data incorrect?   1) Improper parameter settings; 2) Module data interface is bad.   

d) Why should I use antennas?

The antenna is important in the communication. For this module, the match impedance is 50 Ohm. We have many kinds of antenna for customer to choose, please contact the corresponding sales engineer for help, or find the antenna in our website.

e) What kind of USB bridge board should I use?

The USB Bridge is useful for customers to configure the parameters and simply to do communication test with PC.
