Superheterodyne receiver module with decoding instructions
WR-RY-012-X superheterodyne radio receiver module with decoding , using the French brand RF wireless data transmission receiver chip, is a high cost ISM band receiver module . With high receiver sensitivity , low prices , making some low-end products can only be used to get rid of because of the price restrictions superregeneration module , improved low-end wireless product stability and reliability of improving product quality and image strengthening the competitiveness of products . No external circuit that can do wireless signal is input to the data signal output. Own data decoding circuit, can easily realize wireless product development. Output jog, self-locking, interlocking adjustable to accommodate different users. Manner using the code matches the remote control , you can input 2260,2262,2240,1527 and other chip remote control, supporting convenient.
