Adafruit Feather Adaptor

https://learn.adafruit.com/adafruit-feather/feather-specification. You have to adapt the firmware for using the Feather pinout.

There is a Teensy 3.x Feather Adapter from Adafruit, but I2C and analog pins are different. You have to modify it. You can build your own one from scratch by yourself.
