GPIO pin tolerant to 5V

Post by geraldo.gomes »

Hi,

There is a GPIO pin tolerant to 5V in Odroid C1+?

Thanks a lot.

No. You have to use level-shifter circuits.

Sorry for reusing this old thread.

I have an WS2813 LED strip, with external power supply. The LED strip is 5 V.
Can I connect the data pin to one of the C2 GPIO pins, or could that break the C2? Currently I'm using an Arduino, where the control is working, but the Arduino is 5 V.

If control is input only (on the led side) and 3.3V tolerant, then it should work. Search how the RPI folks are connecting to led strips. If it works directly on RPI, it works on odroid too.

After much more searching I finally found a tutorial that states it should work. Will soon try it, once I get the neopixel python library to load. But that's another problem outside of this thread.
