Working frequency band: Working in the 5645-5945MHz ISM frequency band. Single chip design: integrated with VCO PLL, Broadband FM video modulation and FM audio modulation make the module small in size and low in power consumption. Output power: There are versions with fixed power of 200mw and 600MW, and some modules have an output power of 22-24dBm. TX5823 is a 5.8GHz A/V FM audio and video transmission module. Channel selection: With 8 channel transmissions, 48 frequency points can be through SPI control, and an additional 24 U O H frequency points can be added by oneself. Low power consumption: Typical power consumption is 3.3V 330mA. High stability: Built in frequency phase-locked loop, high stability. Low harmonic radiation: Low radiation, minimal interference to surrounding equipment. Direct input signal: It can directly input analog audio and video signals. Widely applicable: Suitable for unmanned aerial vehicle image transmission, quadcopter, baby monitoring, construction site image monitoring, wireless camera security system, wireless imaging medical equipment, wireless visual reversing camera transmission, wireless video toys, wireless doorbells and other occasions. Application: Drone image transmission:can be used for FPV(first person perspective)flight,allowing the operator to see the real-time footage captured by the drone,enhancing the flight experience and operational accuracy. Security monitoring: In construction sites and wireless camera security systems,wireless transmission of images can be achieved for convenient monitoring and management. Baby monitoring: convenient for parents to observe the baby's movements in real time,ensuring the safety Application: Medical equipment: can be used for wireless imaging medical equipment, facilitating medical operations and diagnosis. Toys and entertainment devices: such as wireless video toys, game to TV conversion, etc., increase the fun and convenience of toys and entertainment devices. Wiring definition: AUD: External audio input RX: Parameter tuning, connect to flight control for any TX VXX: Battery powered input positive GND: Battery powered input negative VID: Video input 5V GND: The onboard BEC 5V output can provide power to the camera usage method: The general TX5823 module is already SPI controlled for frequency selection from the factory, so there is no need to remove the 1k resistor on pin 1 and the 10nf capacitor on pin 26 of RTC6705 by yourself. Supports remote parameter tuning of SmartAudio protocol on the flight control end, and can also use buttons (LED status indicators) to change frequency bands, channels, and power. The meaning of the three LED indicator lights: the red light indicates the working status, and the green and blue lights indicate the current channel, frequency, and power. The circuit board printing is slightly different, which does not affect the use.
