The MPU-6050 sensor operates at 3.3V. but the GY-521 module contains a 3.3V regulator so the module should be supplied with 5V on the VCC pin. Since the module uses I2C which is open-drain with pull-ups to 3.3V, level translation is generally not considered necessary when using it with a 5V MCU.

Googling I found this :

You can use my example https://www.b4x.com/android/forum/t...nts-mpu-6050-and-magnetometer-hmc5883l.65917/ , no need for any library.

If you use Arduino- connect SCL to A5, SDA to A4, 3.3V and ground
If you use Wemos or Nodemcu - connect SCL To D2 And SDA To D1.
The MPU is using the rWire library so check where to connect for rWire in any other board.

Hi
I used your library.
When I want to upload show this error.

Can you please look into the matter,

SoftwareI2C.cpp:31:10: fatal error: SoftI2CMaster.h: No such file or directory
#include <SoftI2CMaster.h>
^~~~~~~~~~~~~~~~~
compilation terminated.
exit status 1

I want to make a quadqupter and this library is very very necessary for me.
