  • SV651 500mW Industrial Anti-interference Wireless Data Transmission Module TTL/RS232/RS485 433/490/868/915 MHz
  • Description
SV651 is an Industrial class & highly-integrated RF transceiver module, which adopts the highperformance Si4432 from Silicon Labs and industrial micro-controller . TTL / 232 /485 can bechosen corresponding to SV651-TTL / SV651-232 / SV651-485. SV651 has good sensitivity and500mW output power to achieve long RF range and reliable RF communication. To avoid theinterference, SV651 provides 40 frequency channels and configurable Net ID. SV651 is flexible buteasy to use , it comes with many parameters, such as: frequency, data rate, output power, Net ID,Node ID. Users can configure the parameters through PC or customer’s own device.

Electrical Characteristics


 

Typical application:

 

Operation

1) Power on Reset

After powered on reset, the TX LED (Red) and RX LED (Blue) will blink 3 times. The total reset

time is around 2s, as below:

Note:Contact us to customize if you want to shorten the POR time.

2) Sleep mode

After Power on Reset, the module enters into sleep mode when CS pin is pulled low. In this mode,

the current consumption is very small. In Sleep mode, the module can’t do any communication and

cant’ be set even Set Pin is pulled low. All the parameters will be kept unchanged in Sleep mode.

User can wake up the module by pulling high the CS Pin.

3) Working Mode

The CS and SET Pin is internally pulled up. Pull CS pin high or leave it open will make SV653 enter

into working mode.
