ASK Radio Transmitter Module

As a superior performance transmitter module for ISM band, our RCT02STX8 ASK radio transmitter module comes with advantages of high power transmission and low voltage power supply. Due to its superior quality and performance, this product easily passes the Fcc or CE authentication. With the adoption of European brand RF wireless data transferring or receiver chipsets, it is able to convert wireless signal input to data signal output without any external circuit. Users just need to decode the data by a simple circuit and then any wireless product development can be easily achieved.

This product can find its applications in remote keyless entry, wireless security alarm, remote control curtain, wireless industrial controller, wireless data transmission, and remotely open doors, barriers, gates, etc.
