I'm planning my first Arduino project which involves a MPU-6050 accelerometer(3.3V) and a RGB led(5V). I've found this Arduino Clone but i'm not sure if it has 3.3V and 5V outputs that I can use. The pins do exist on the original Leonardo board but i'm not sure if the clone contains them as well.


That has a 5V pin (Vcc) but no 3.3V. Also the 5V pin can't provide more than a few hundred mA.

  • I see, thanks a lot. If I find a 5V accelerometer would I be able to connect it + the led to the same 5V pin? – Paul Etscheit Jan 10 '17 at 23:26
  • Yep. Note that a 5v accelerometer will probably be a 3.3v one with built in 3.3v regulator, so you need to take the same precautions as a 3.3v one. – Majenko Jan 10 '17 at 23:27
  • What kind of procautions do you mean? Could you maybe give me term to google to send me down the right path? – Paul Etscheit Jan 10 '17 at 23:32
  • Logic level shifting. Interfacing a 5v Arduino to a 3.3v device. If the accelerometer is I2C include that in your search too. – Majenko Jan 10 '17 at 23:33
