1pc/lot SV650 433MHz RS485 Embedded 500mW Si4432 RF wireless transceiver module

Product details

SV650 is an embedded ultra-small size of the high-power high integrated wireless module, using high-performance Silicon Lab Si4432 RF chip. Receiver sensitivity coupled with low industry-leading 500 mW output power guaranteed expand the scope and improve the link performance. Module provides a multi-band multi-channel and network ID to reduce interference during transmission to improve the transmission performance. Users can connect via PC software or devices via the serial port, and an RF Online is set to modify the relevant parameters.

Accessories:

 Antenna: The antenna is an important part of the communication system. Its feature directly affects the performance of the communication system. The match impedance of module is 50 ohms, we recommend that users adopt standard spring antenna.

 USB Bridge board: Modules needed by configuration tool to configure the relative parameters. The Company supplies a USB interface matching plate adapter with TTL/RS485 level, so that users can quickly and easily with the PC side communication.
