  • There's a drop of soldering paste just above the ADD0 pin on the new breakout board layout. Use some soldering wick and a soldering gun to remove it and the Universe will be spinning again. You will be able to use the ADD0 pin just like on the old board (attach it to GND, VCC, SDA, SCL to obtain up to 4 I2C addresses). Do not attempt to connect the ADD0 directly to VCC without removing this "jumper" as it will create a short between VCC and GND and will probably end up toasting something in your circuit (depending on the connections you have there).

  • How much does this weight?
