RXB22 ASK superheterodyne wireless receiving module, using imported wireless receiving chip, is a cost-effective ISM band ASK receiving module. It has high receiving sensitivity and low price. It can be widely used in low-end products to replace super-regenerative modules, improve the stability and reliability of low-end wireless products, and strengthen product competitiveness. The data port can be directly connected to the I/O port of the single-chip microcomputer or the data signal input end of the wireless decoding chip, which can directly realize the function of wireless signal to data reception. Makes the wireless product development and production process easier and faster.
