Combined Pin Assignments card
To plan Teensy projects, I just combined the pin assignments from the back and front cards and added:
- The port pins from the schematics (useful for byte transfers such as parallel LCDs),
- A free area for each pin to plan the connections in your project.
It could look better if I could identify/get the font used by Paul...
You may find it useful for some of your projects.
suggestion... In green box leftmost, marked "SPI Port": Replace "SPI Library" with text showing the correspondence of DIN and DOUT to MISO and MOSI. Or better, somehow cram that in to the notations near pins 11, 12.
I will wait a few days to gather comments and then make the changes.
For my personal use, I created some spreadsheets to keep track of the pins on different micro-processors. It just a text spreadsheet, no fancy graphics, but it allows me to tell at a glance what pins to use for what. Feel free to use any information from it. Here is the page for the Teensy 3.0 and 3.1: https://docs.google.com/spreadsheet/...WamxfckE#gid=0
I've added a link on the main pinout reference page to this and 2 other alternate pinout threads.
Hopefully these links will help everyone find it.
Thanks Paul for adding the info on the pin assignments page so quickly!
For those who want to modify the pdf, here is the original svg file (easily editable with Inkscape).
Pin labeled AGND
There is a Teensy 3.1 pin labeled AGND. What is it for? What does it do?

So if I am reading potentiometer values, is it recommended that I use AGND as the ground for the pots or would the normal ground suffice?
And if the pots are read via a multiplexer does the mux chip ground go to normal ground or AGRND?
