About the Product
433MHz 100 Meters ASK Wireless Module Kit RF
This 433MHz 100 Meters ASK Wireless Module Kit RF comes with a SRX882 Receiver Module, STX882 ASK Transmitter Module and SW433–TH32 spring antenna. The modules can be connected to the microcontroller directly. So it is more convenient for user developing wireless products.
STX882 is a low cost, small size, ultra-high-power, low harmonic ASK transmitter module. Has high stability and high cost, at 3.6V power to achieve 50mW.
SRX882 is a micro power strong driving force super heterodyne receiver module. Has high stability, anti-interference and high cost-effective, but also has a powerful driving force.
