Power Pins

The motor driver/controller on the breakout requires 3-5V power. You can use either, whichever logic level you use on your embedded processor

  • Vin - To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V
  • GND - common ground for power and logic

I2C Pins

  • SCL - I2C clock pin, connect to your microcontrollers I2C clock line. This pin can be used with 3V or 5V logic, and there's a 10K pullup on this pin.
  • SDA - I2C data pin, connect to your microcontrollers I2C data line. This pin can be used with 3V or 5V logic, and there's a 10K pullup on this pin.

Other!

  • IN/TRIG - This is a general purpose pin that can be used for a couple different uses. One use is to read analog audio in to control the audio-to-haptic code. Another use is to 'trigger' the effects to go rather than sending a I2C command.
