Teensy to Arduino adapter board

OSH Park engineer Dan Sheadel created this board to break out Teensy 3.x into a form factor suitable for small electronics prototyping:

  • Adapts Teensy pinout to Arduino shield, so existing shields can be fit to a Teensy
  • Adds LiPo battery monitoring and charging capability
  • Adds three wire pinouts for all pins
  • All PWM outputs have an LED
  • All PWM outputs connect to 3 wire servo headers that supply input or battery voltage for use with servos or motor controllers
  • Contains small Stormy logo on back since the Stormbots were the inspiration for this board’s existence

BOM

Due to the nature of the breakout, many components can be omitted depending on the needed sections.

Components

Pin Connections

The various use cases may or may not require some or all of these pins. Here’s the most you can solder to the board in the simplest orientation

Most of these can be swapped, omitted, or assembled with small 1×3 connectors or whatever you have on hand. Otherwise, they can be purchased at Digikey or Adafruit
