Teensy 3.x Feather Adapter

Oh man, is this not the best thing ever? You can now use the awesome Teensy 3 with any and all of our FeatherWings or Feather accessories and even get built-in LiPoly charging!
This Feather adapter rearranges the pins of a Teensy 3.x to give you the same shape and pinout for the Feathers. Adafruit have tested their FeatherWings so far and all are drop-in compatible. It's a great way to take advantage of the Feather ecosystem. Give your Teensy a stepper/DC motor driver, GPS, LED matrix or OLED add-on with ease. With the space left over, they even added in a 500mA LiPoly charger that automatically charges over USB and will switch over to the LiPo when USB is unplugged. There's also a 100K resistor divider for monitoring the battery voltage connected to A7
Comes with one assembled adapter, shorty headers for attaching your Teensy 3, and both standard and stacking headers so you can use your Teensy in a breadboard and even plug a shield on top. Some soldering is required!
Teensy 3.x and LiPoly battery not included! (But we do stock them in the shop for your convenience)

Rev A accidentally connects the Teensy's RTC VBAT pin to the Lipoly Battery, which may overdrive that pin - to resolve simply do not solder in the Teensy's VBAT pin when assembling!
