Hello,

Thank you Michel. GTK. Can I ask a question related...

My Gyro is 5v (ADXRS300) with ST1, ST2, TEMP, 2.5V, RATE, GND, 5V..

Can someone please give the pins to connect to the Tiny on ADC2? 

5v is easy -> +5v on Tiny
GND -> GND on Tiny
....
Without any instructions on the Wiki about the connector and going by the funjet1.xml airframe file given I had it connected to ADC1 
GRYO ---- TINY
GND -> GND
RATE->ADC3
5V->+5v 
I hope I didn't damage ADC1 on the Tiny

Thank you,
-David

So, if I were to connect my 5v Gyro into

Hi,
For sure, you can use this ADC with a Gyro (or  other analog sensor) but this is a 3.3v max input level, so if your gyro  is a 5v, don't forget the resistor bridge...or use  ADC5 or ADC6 : these inputs have their own on-board resistor bridge.

Hi guys


 I was wondering, on the "USB" port on TinyV2 has a ADC_7, could I use this
chaneel for connecting roll gyro?





Thanks
