Product Description

รีโมทคอนโทรล 3 CH -rf transmitter and receiver module wireless remote control system


The high quality super heterodyne receiver AK-RXB12-X, use the French brand RF wireless data transfer receiver chips, so it is a high cost performance of ISM frequency channel receiver module. High receiving sensitivity and low price enable the low end wireless products get rid of the high price limit, furthermore, it improved the stability and reliability of the low end wireless products,also the quality and image of our products,thus made our products more competitive in the market.Moreover,with no plus any circuit can make the RF signal input to data signal output.In order to make a new design only a simple data decoding circuit you need .

When drive the MCU directly ,the I/O port cant connect the pull-up or pull-down resistors because the drive current of RXB12s data output pin is weak.Also the inner pull-up or pull-down resistors of MCU should be disabled.
