Reference Configuration

Since it is possible to change some characteristic of the unit selecting different hardware, we propose a reference configuration. The reference configuration will have the following characteristics (complete hardware). This unit can determine True Airspeed, Mach number, Altitude, and common air properties from a pitot-static probe data and an outside air temperature probe.

Overall weight: 47 grams

Overall dimensions: Without push in fittings 66x41x24 mm; With push-in fittings 81x41x24 mm. Fixing tabs dimensions are equal to those of a standard servo

Assembly time: About 1.5 hours

Overall cost: 160 Eur (June 2017)

Power and Supply Current: Power to the ADC is supplied through a standard micro USB port, the same can be used to transfer data. Typical power source is a cell phone power bank
