I bought this MPU-6050: link (marked as "GY-521" on the board)
According to the manufacturers' site, the sensor logic level is 3.3V (though the eBay page says
Power supply :3-5v)
Should I use a 4 channel Bi-Directional Logic Level Converter (like this one) for the
SDA, SCL, INT channels? or can I connect it directly to my Arduino Nano?
I saw some places that says I should use it with a logic level converter and some who say it's ok without it. (I guess it depends on the sensor board, so please take a look, link above)
SDA <-> LLC <-> A4 SCL <-> LLC <-> A5 INT <-> LLC <-> D2 VCC <- LLC <- 5V (arduino) GND <- LLC <- GND (arduino)
I still don't have the parts so I can't test it, and I'm probably going to use Jeff Rowberg library to communicate with the sensor (I2C)
