TX5823S 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. The chip 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, plus an external RF amplifier can modulate 3W-10W power Low power consumption: 5V 290mA Transmitting power: 19dBm to 21dBm 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 Note:SPI control: You can develop your own frequency through our module, the highest frequency can reach 48CH (The product appearance and printed words depending on the batch, but this does not affect use) Color: As shown Material: PCB Package Contents: 1 x Transmission Module Only 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. The measurement allowed error is +/- 1-3cm.
