Description
433M Wireless Digital Audio Module Wireless RF Radio Receiver Guitar Wireless Microphone Transmitter and Receiver Kit
Product Description
Using the latest 433M line transmission technology, 44.1K sampling rate, 16bitAD sampling to achieve lossless high-fidelity digital mono audio transmission, 7 groups of optional frequency channels. The farthest distance in open ground is about 150 meters. One receiving and one sending can form a wireless audio transceiver system, which is simple and convenient. Can send and receive multiple at the same time.
Function Description
Input signal: analog tone Output signal: analog audio Working voltage: 5V5V (please specify if you need 3.7V power supply) GFSK digital modulation/demodulation method 20Hz~ 20KHz frequency response 90dB audio dynamic range 45dB adjacent channel rejection, 30dB image rejection 20Hz~20KHz frequency response 44.1K digital audio sampling rate, 16bit sample quantization level Long transmission distance: transmission of mono sound audio data within 150 meters of open area (static point-to-point) Support multiple transmission modes of point-to-point and point-to-multipoint (that is, one sends multiple simultaneous receptions), multiple alternative frequency bands, easily avoid interference frequencies: this product works in the 433M ISM (ie industrial, scientific, medical) frequency band , There are 7 optional frequency points, in order to avoid the interference that is easy to appear on the 2.4GH2 public frequency band to affect the sound quality, the product provides a frequency point selection function, if the product has been working During the process, strong noise appears, that is, when there is interference at the current frequency point that affects the output sound quality, a new working frequency point can be selected to maintain a good use effect of the product. Transmitting power: 10mw Transmitting module working current: 85mA Receiving sensitivity -88dBm receiving module working current 45mA Module size 26x50mm
