I have this shield, and the MISO pin does not go trough the HEX converter.
I need to use 1 arduino mega(5v) as master 1 sd shield(3.3V) and 2 arduino pro(5v) all connected on SPI
the problem is that when all connected the MISO pin of arduino pro has 5V and the card Miso pin is 3.3V.
individually both work.
How can I make these work together?
No public wish lists :(
