How do i wire an the analog airspeed sensor (3 Pins, 5 Volt) to the new Pixhawk 2.1 board??? There is no ADC 6.6V connector…
Thank you very much
In this post, a pinout document is linked which suggests the ADC is for 5V analog sensing: Telemetry Wiring
Here’s a 2nd attempt at the dropbox link: https://www.dropbox.com/s/1rzjsxzrzx8onf9/PixHawk%202%20Connector%20Pinout%20-%20Leo%20Technologies.pdf?dl=0
Hello,
I have the same problem, I’m wondering if you could guide me through that?
Thanks!
It is as simple as adding two resistors in between your sensor (0 to 5 volts outputs) and the pixhawk 2 ADC input. 
Will cost you a whooping five cents! 
Cheers

Of course you can power your sensor (if compatible voltage) from the same ADC little 3 pin JST GH 1.25mm connector.
What kind of sensor is this analog sensor? I have an Pihawk airspeed sensor I got a long while ago for the Pihxawk “1”. Looks exakt like this: https://i0.wp.com/ae01.alicdn.com/kf/HTB1fVs3LXXXXXcjXpXXq6xXFXXXD/Quad-Pixhawk-PX4-Differential-Airspeed-Sensor-Kit-Pitot-Tube-Airspeedometer.jpg?crop=5,2,900,500&quality=2880
And its called Pixhawk PX4 Differential Airspeed Sensor.
Will that one work on Pixhawk 2.1? (Hexaero Cube).
Hi Henrik04!
I’m trying to wire a analog air speed on pixhawk2.1. Do i have to disable battery measurements? Which virtual PIN is used on Pixhawk 2.1 for ADC port ? Tks!
