Hey All,
I’ve listed my SD card level shifter modules on tindie, They allow you to
plug a 3.3v SD card into a 5v arduino without frying the poor innocent SD
card.
If anyone is interested in one, I’ve added a discount code for hacman
members for free shipping, and a quid off if you grab one from me in the
space: 90BBAFB.
Ta,
Bob
