SV651 is an Industrial class & highly-integrated RF module. TTL / 232 /485 can be chosen corresponding to SV651-TTL / SV651-232 / SV651-485. SV651 has good sensitivity and 500mW output power to achieve long RF range and reliable RF communication. To avoid the interference, SV651 provides 40 frequency channels and configurable Net ID. SV651 is flexible but easy 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.
SV651 strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.
