Excellent,Thank you Michel,Also THANK YOU! ... for taking such time to document the designs so well on the Wiki.When I first started my interest with Paparazzi Tiny1.3 was new...BOM, Pinout, even photos were scarce. I use your Wiki pages exclusively and many many times a day to refer to the pinouts, layouts etc. Questions asked of me are most often replied with URL right to your pages to the pinouts or images or notes.Well done. I'm sure many many people appreciate the time you spent to document so thoroughly. I may not find what I am looking for on the Wiki but I have to at the same time give credit that the latest designs are extremely well documented there.Regards,DavidOn Jun 23, 2008, at 12:57 PM, Michel GORRAZ wrote:Hi,
The easiest way to connect a ADXRS300 on a Tiny v2 (or a Twog) is to use ADC5 on the "ADC2" connector
- GND on GND (pin #1)
- +5V on +5v (pin #2)
- Rateout on ADC5 (pin #5) => resistor bridge for 5v sensor is included for this ADC on the Tiny V2
And... that all !
Don't worry, ADC1 is probably alive :)

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 TinyGND -> 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 ADC1GRYO ---- TINYGND -> GNDRATE->ADC35V->+5vI hope I didn't damage ADC1 on the TinyThank you,-DavidSo, if I were to connect my 5v Gyro intoOn Jun 23, 2008, at 8:29 AM, Michel GORRAZ wrote: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
Chen
