Triple Axis Accelerometer ADXL345. I have found this Accelerometer and board not communicating on I2C bus. After some research, I found by grounding INT2 & setting CS to 3.3 Volt and wiring the I2C pins as per specification in pdf to work on the I2C bus.

Hi @Peter250114 - welcome to the forums 🙂  
Doe that mean you’ve found a way forward and the accelerometer is working now?
