The default I2C address is 0x5A.

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 Logic Pins

  • SCL - I2C clock pin, connect to your microcontroller's I2C clock line. This pin has  a 10K pullup to VIN.
  • SDA -I2C data pin, connect to your microcontroller's I2C data line. This pin has  a 10K pullup to VIN.
  • STEMMA QT - These connectors allow you to connect to development boards with STEMMA QT connectors, or to other things, with various associated accessories.

Motor Input

  • Motor Positive (+) - positive input for a haptic motor
  • Motor Negative (-) - negative input for a haptic motor

Other

  • INT - 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.

Power LED and Jumper

  • Power LED - In the upper left corner, above the STEMMA connector, on the front of the board, is the power LED, labeled on. It is the green LED.
  • LED jumper - In the upper right corner on the back of the board is a jumper for the power LED. If you wish to disable the power LED, simply cut the trace on this jumper.
