5V logic and IO bricklets

[riklaunim]

IO-4 bricklet is at 3.3V so I would have to use a logic level converter (I have this one) and provide 5V to the external board on my own. Would that work?

 

IO-16 can do 5V but won't provide 5V without step-down power brick. If I provide 5V to the external device can IO-16 handle 5V logic without the power brick?

You can use the TXB0108 together with the IO-4.

 

The IO-16 can withstand VDD + 0.6V. That means, if the 5V-rail of the IO-16 Bricklet has a voltage of 4.7V, you should apply a maximum of 5.3V from your external device.

 

Short answer: Yes.
