Btw. the Vcc on the SPI is 5V and should be noticed
On the spi in the middle?, SHIT!, And I have been using this and that.
How can I know if my board is defunct or not ?
I was attaching an unit that is supposed to handle 3v3 and 5v, but I tried mosi++ in the middle, and the same on the edge of the board.
Mixing 5v and 3v3 on an board that is not 5v tolerant is not very nice design!
