DRA886TX and DRA887TX are low cost ASK transmitter modules which are based on RFIC which minimizes the board size and improve the stability against nterferences. The transmitter modules work in very wide voltage range so they are very suiable for battery-driven applications. DRA886RX is a type of high sensitive ASK receiver which works at 3.6~5.5V. It can be used together with DRA886TX and DRA887TX to construct simple and short range wireless control system.
