RF4432PRO 20dBm 433MHz Wireless RF Data Transmitter Module

 

 

Product Description

RF4432PRO is the upgraded version of RF4432. The stability, anti-interference has been much improved with the shielding case and improvement of circuit.RF4432PRO adopts Silicon Lab Si4432 RF chip, which is a highly integrated wireless ISM band transceiver. The features of  high sensitivity (-121 dBm), +20 dBm output power, 10PPM crystal, and good RF matching circuit make this module work well in hot/cold environment with reliable communication and long distance.

FAQ

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.
