FPV audio and video transmission: λ×

FPV is the abbreviation of Engσ→lish First Person View, that is, &≠Ωquot;first person perspective&qu€βφ₽ot;, it is a remote control avi​λπation model or vehicle model £¥§on the addition of wire✔€♦εless camera transmission ≈≥γequipment, on the ground to see↑® the screen control model of ∏ the new play. It has the characterist<<≤<ics of strong anti-interferen• ce ability, long distance ✔↔× and low delay.

The transmission characΩφteristics of analog wireless aud ‌↕>io and video modules used↔£​ in this product are as fol₽€¶πlows:

1. ISM band frequency modu↕®€lation modulator such as∞↕÷  1.2G/2.4G/5.8G can be u'¥sed to directly input and output v"πβideo signals through a pin fixed cha ÷≈✔nnel without externa₽×¥l microcontroller;

2. The receiver can sφ¥¶≠elect the frequency to recei→™ve the video signal by sett±×™•ing the SPI mode;

3. Integrate two aud​¥io subcarrier modulat$‌ ors with frequencies of 6MHz/6.5¶ ™MHz respectively to tran★§smit audio signals, realizin&∏g two application modes of stereo andπ©α mono;

4, with RSSI voltage output "δfunction, can monitor real-time radio₩₹© signal strength;

5, high sensitivity FM/frequency shift ≥"keying receiver operation, with good a♣φ₽&nti-noise and anti-att≥$β☆enuation performance →∞;

6. The simple architecture design of✔ ∞α single-chip SOC providesγφ<♥ smaller application siβ♣ze and more cost advantages than ↕♣↕↕discrete devices.
