Embedded Teensy 3.1 / schematics correct?

[Paraglider]

Is this schematics for an embedded Teensy 3.1 correct?



Analog read is just used to monitor battery voltage, all other signals are digital, I2C. I tried to simplify the schematics as much as possible. But the question is if I got everything right.

Your VREF_OUT doesn't look right. Should that not be going just to a cap and not to VDD?

Thanks for the advice. VREF_OUT should be wired correctly now.

The other thing I've just noticec is that you ars using a teensy 3.0 processor and not a 3.1 processor. So just be carfull about the DAC pin change that is available on the teensy 3.1

ok, thanks for the advice.

hey have you finished the schematic for the 3.1? I am trying to make a version too in eagle, but don't have the proper experience like you do. Can you share your schematic file?
I would really appreciate it!

@SDTricker - This may be too overly obvious, but if you haven't already fully developed your project using an ordinary Teensy 3.1 and all other components on a breadboard, you really should do that first.
