Product Description
2sets 500mW 3km distance radio modem SV652 rs232 wireless data transceiver modules


SV652 is highly-integrated RF module, which adopts high performance Si4432 from Silicon Labs. It has 3 optional Interfaces (TTL, 232, 485). SV652 has high sensitivity and 500mW output power to achieve long RF range and reliable RF communication. SV652 comes with many parameters which are configurable, such as: frequency, data rate, output power, Net ID, Node ID. Users can configure the parameters through PC or customer’s own device. The features of long distance,wide working voltage and simple parameters configuration make SV652 wildly used in many fields.

Order List
2pcs SV652 modules
2pcs antennas 
The antenna is very important for RF communication,We have many kinds of antenna for customer to choose,please contact the corresponding sales engineer for help.
Tips for antenna:
Don’t close to the ground, metal, magnet, big current:
If you are using the sucker antenna, pull the wire as straight as possible, the sucker foundation should stick with metal 
2) USB bridge board 
There are 3 type of USB bridge,which is SU108-TTL/SU108-232 /SU108-485.SU108 -TTL is of TTL Interface,SU108-232 is for 232 Interface,SU108 - 485 is for 485 Interface.
User should select  the right USB bridge board corresponding to the RF module.
