GPi 3V3 to 5V0 level shifter board testing notes

Now I have used ULN2803 x 2 and LVC245 x 1 to level shift the 3v3 16o8i signals to 5V0.

The gz_16o8i output signals are indicated by the red LEDs, and input by the yellow LEDs.  I used jumper to short the ground to test that the 8 input connections are OK.

So far so good.  Lunch time.
