We have added support for the Illyrian pulse oximeter to the Aithre Shield EX 3.0. This means that the EX 3.0 now wirelessly collects both oxygen levels of the pilot AND portable oxygen tank pressure and puts both on the avionics with CO ppm data. The EX 3.0 is fully compatible now with Dynon Skyview (SV-EMS required) and with Garmin G3x (GEA 24 required). Wiring is simple and easy and the EX 3.0 weighs only 1 ounce and is just 1.75"x1.75"x0.7" in size.
