RX5808 is an FM audio and video receiving and demodulating module that works in the 5645-5945MHz ISM frequency band (or uses SPI mode to control the frequency band through an external microcontroller) Using a single-chip design, the chip integrates VCO, PLL, broadband FM video demodulation, and FM audio demodulation, making the module small in size, low in power consumption, and high in sensitivity Adopting a patch package, it occupies a very small space of the whole machine Just simply connect the power supply, audio cable, video cable, and connect the antenna to receive sound and image signals High receiving sensitivity: 5dBm to -91dBm, built-in frequency phase-locked loop with high stability<br><br>Receiving frequency: 5625-5945MHz; 8 channels Receiving sensitivity: 5dBm to -91dBm Specification:RX5808+no audio+SPI mode The product appearance and printed words depending on the batch, but this does not affect use.
