michinyon:
does your device have 2 power input pins ?The ones I have, will take 5V at VIN and put through a regulator device that the chip uses
OR they will take 3.3 V at another pin, and use that directly, without using the regulator.If you put 3.3V to the vin pin, it probably wont work.
Your device may be different.
My device (MPU-6050) has VCC, GND, SCL, SDA, XDA, XCL, ADO, and INT.
Arduino due has Vin, 3.3v, and 5v.
I connect VCC(MPU-6050) to 3.3V(Aruduino due) without using the pull-up or pull-down register.
Does this answer your question??
I am inexperienced in English, so do not have confidence.
