RX5808 is an FM audio and video receiving and demodulating module that works in the 56455945MHz ISM frequency band (or uses SPI mode to control the frequency band through an external microcontroller)Using a singlechip 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 sensitivityAdopting a patch package, it occupies a very small space of the whole machineJust simply connect the power supply, audio cable, video cable, and connect the antenna to receive sound and image signalsHigh receiving sensitivity: 5dBm to 91dBm, builtin frequency phaselocked loop with high stabilityReceiving frequency: 56255945MHz; 8 channelsReceiving sensitivity: 5dBm to 91dBmSpecification:RX5808+no audio+SPI modeThe product appearance and printed words may vary depending on the batch, but this does not affect use.Colour:Random Color(The color is random, and the designation is not accepted)Material:PCBSize:28x23x3.5mmPackage Contents:1 * Receiver ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
