ADXL345 Triple Axis Accelerometer (GY-291) Dead on arrival.
Thanks for posting your question here. It is a lot easier to work out if it could just be a simple fix when it’s written in front of you. It does look like you’ve done everything right, and if you’re seeing the correct data being written out from your Pi, and you’ve confirmed the voltages on board, it sounds like you’ve tried everything.
If you reply to your order confirmation email with a link to this forum post, we can go from there.
