MPU 6050 wiring


I’m trying to connect the MPU 6050 breakout board to my Olimex LPC 1343, which works at 3.3 V put can be powered at 5 V.
I saw the image for the connection with a 5V Arduino which uses the 5V pin for the connection to the power.
I connected a 3.3V line to the MPU 6050 pin labeled as “3.3V” but the I2C slave always gives a NACK.
Do the power line be connected always to the 5V pin?
Is it possible to use a 3.3V line for this purpose?


Yes it’s possible. You have just coonect the 3.3V supply and the ground for alimentation. Next you use the SCL and SDA.
