Interconnection

Solder four wires to the I2C pins on the Backpack. The colors I used in the picture above are the same as the ones in the circuit diagram on the previous page.

  • Red: VCC
  • Black: GND
  • Blue: SDA
  • Yellow: SCL

Connect the four wires to the Pro Trinket and PowerBoost as listed below:

  • Red: 5V on the PowerBoost
  • Black: GND on the Pro Trinket
  • Blue: A4 on the Pro Trinket
  • Yellow: A5 on the Pro Trinket

Finally use some super glue to secure the eight magnets to the cavities on the enclosure. Wait for a little bit to allow the glue to dry completely.

The two pieces snap together easily, and we've finally finished the entire assembly process!
