SV652 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 be chosencorresponding to SV652-TTL / SV652-232 / SV652-485. SV652 has good sensitivity and 500mWoutput power to achieve long RF range and reliable RF communication. To avoid the interference,SV652 provides 40 frequency channels and configurable Net ID. SV652 is flexible but easy to use , itcomes with many parameters, such as: frequency, data rate, output power, Net ID, Node ID. Userscan configure the parameters through PC or customer’s own device.

SET |
Configuration mode enable (low to enter into the setting mode, leave open or connect high level to exit setting mode) Valid when CS Pin is high or leave open. |
| 6 |
CS/NC |
For the default version of the module, this pin needs to be left floating (the module has a built-in anti-crash self-reset circuit) Note: Customers can customize the sleep version of the program (without self-reset function), low level sleep, current lower than 5uA, default high level output. |
