I’m trying to interface Z1 with 5V TTL signals using either the PMOD connector or whatever it has. Since the board doesn’t support signal level >3.4V, I will need a level shifter. As I searched around, all such things I found requires double power supply 3.3V and 5V. I hope to let it work alone where there’s no 5V power supply. Can anyone recommend a decent level shifter that:
- has at least one channel, and
- has an on-board booster that generate 5V from 3.3V which I can get from Z1, and
- working frequency >1MHz (10MHz better, 100MHz great), and
- (would be better) can mechanically connect to the board firmly. Maybe two-row connector on the board will make connection stronger.
Any advice is appreciated.
