TX5813 is an FM audio and video transmitter module that works in the 5645-5945MHz ISM band (or uses SPI mode to control the band through an external microcontroller). The module adopts a single-chip design, which integrates VCO, PLL, broadband FM video modulation, and FM audio modulation, making the module small in size, low in power consumption, and high in sensitivity; the module adopts a patch package form, which occupies a very small space of the whole machine. The application of this module only requires a simple connection of power, audio cable, video cable, and antenna to transmit sound and image signals. 5.8G broadband FM audio and video synchronous transmission Small size SMD package: 19x22x3 mm Low power consumption: 5 V 110mA Transmitting power: 10dBm to 20dBm Direct input of analog audio and video signals 8-channel transmission SPI control (48 frequency points) External RF amplifier can modulate 20mW-10W power Applications: FPV model aircraft audio and video wireless transmission; Baby monitor; Construction site image monitoring; Wireless camera security system; Wireless imaging medical equipment Wireless visual reversing camera transmission Wireless video toys Wireless doorbell Due to different batches, there may be differences in product appearance, color, and printed text, which not affect the use.
