{"product_id":"frsky-vari-adv-variometer-telemetry-sensor","title":"FrSky VARI ADV Variometer Telemetry Sensor","description":"\u003ch1\u003eFrSky VARI ADV High Precision Variometer Telemetry Sensor\u003c\/h1\u003e\n\u003cp\u003eLook, we know you think you have the eyes of a hawk and the instincts of a migratory bird, but let’s be real: you’re standing in a muddy field in the UK squinting at a dot in the sky. The \u003cstrong\u003eFrSky VARI ADV Variometer\u003c\/strong\u003e is here to tell you exactly how high that dot is before you accidentally breach CAA altitude limits or lose it in a cloud. Updated for the modern era with FBUS support (because S.Port is so 2015), this \u003cstrong\u003etelemetry sensor\u003c\/strong\u003e gives you real-time altitude and vertical speed data. Essential for glider pilots hunting thermals, and equally useful for quad pilots who just like seeing numbers go up on their OSD.\u003c\/p\u003e\n\u003ch3\u003eWhy You Want It\u003c\/h3\u003e\n\u003cp\u003eBecause guessing your climb rate is for amateurs. This little PCB measures atmospheric pressure changes with a resolution of 0.1 meters, which is roughly the height of the grass you’re standing on. Connect it to your FrSky receiver via FBUS or S.Port, and your Taranis (or whatever OpenTX\/EdgeTX radio you’re clutching) can scream at you when you hit a thermal. It supports daisy-chaining, so you can wire up a spaghetti monster of sensors—Voltage, RPM, GPS—all on one line. Just don’t wire it backwards; the manual explicitly states they aren’t responsible for your \"magic smoke\" moments, and neither are we.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0914\/9972\/5181\/files\/FRsky_Vari.jpg?v=1763396181\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.4g (Your drone won’t even know it’s there; your ego might).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 40 × 21 × 6.5 mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range:\u003c\/strong\u003e -1800m to 10000m (If you hit 10km, please tell NASA we said hi).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResolution:\u003c\/strong\u003e 0.1m (High precision, assuming the weather doesn't change mid-flight).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e 4V – 10V DC.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Draw:\u003c\/strong\u003e 4mA (Less power than the LED blinking on your flight controller).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtocol:\u003c\/strong\u003e FBUS \/ S.Port (Auto-detected: LED flashes slow for S.Port, fast for FBUS).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0914\/9972\/5181\/files\/FRsky_Vari2.jpg?v=1763396202\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch3\u003eWhat’s in the Box*\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1× FrSky VARI ADV Variometer Sensor\u003c\/li\u003e\n\u003cli\u003e1× Cable Set (Plug-and-pray ready)\u003c\/li\u003e\n\u003cli\u003e1× Manual (which you are currently ignoring by reading this)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures and Highlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDaisy-Chain Ready:\u003c\/strong\u003e Link it with other ADV sensors.
