MPU 6050 /ADXL 345 with Basys 2

Jump to solution

I am trying to connect MPU 6050/ ADXl 345 to Digilent Basys 2 board and get data using I2C. Can I directly connect them to the JA,JB, JC or JD ports. Those two sensors works on 3.3V, Do I need to use resistors or anyother components to make changes to voltage levels.

3.3V is perfect for the Basys 2; you can plug them straight into any of the J? ports.

 

However, for I2C you will need pull-up resistors connected between each of the communication wires (SDA and SCL) and VCC (3.3V). 4.7K is normally a good value. Some of the little MPU6050 or ADXL345 evaluation kits include these; if yours don't then you'll have to add them.
