GPIO 1.8V to low

Unread post by Gerri3d » Fri May 11, 2018 2:14 pm

I would need at least 5V Input / output voltage but better would be 24V. What is the best way to solve this?

The shifter shield allows for 3.3v or 5.0V operation:

Based on the request for 24V, it should be noted that GPIO is not designed to driver large current loads. You will need additionally circuitry to even drive a LED.
Since this TSX0108E chip is a special bi-directional level shifter it does not have strong output pins that can drive LEDs or long cables.
