Anyone know if there is logic shifter shield out there yet to convert due 3.3v to 5v?  there are several older posts on this but havnt seen anything recent other than using a TXB0108.  I have 28 IO to shift and it would be nice if I could find a shield rather than trying to wire in several TX boards.

Hello there!

There is a transistor called a BSS138 that is great for logic level converting. It's really fast and can be used in either direction, so it's great for I2C. You can make a simple circuit and replicate it for each IO pin. Search on Adafruit for a bidirectional logic level converter if you're interested.
Time line? Time isn't made out of lines. It is made out of circles. That is why clocks are round.
