The Teensy 3.x Feather Adapter rearranges the pins of a Teensy 3.x board to match the Adafruit Feather form factor and pinout. This allows the Teensy to work with the full range of FeatherWing add-ons — motor drivers, GPS modules, LED matrices, OLEDs, and more.

The adapter also includes a built-in 500 mA LiPo charger that charges automatically over USB and switches to battery power when USB is disconnected. A 100 kΩ resistor divider on pin A7 enables battery voltage monitoring.
