Teensy adapter Board for NANDway
Hey. in the past, i create a simple adapter board to connect the Teensy to a “360-clip NAND Clip” (the classic kind of NAND Clips). It’s easier and faster to solder a board than wire the cables, no more problems with cable breaks and a good connection. A english speaking user ask me for a solder tutorial, so I thought on this occasion, i can write directly to the community.
Of course, you can find all what you need below to order your own boards.
But now the tutorial with some words (the most things should be self-explanatory).
