I'm trying to investigate what writes well on silkscreen. As you can see, ink smudges badly on silkscreen and ballpoint doesn't write well.

Maybe a marker would do better

Each pin is connected to a 0603 pad and a Normally Open (NO) pad. One end of the 0603 pad is connected to the pin, and the other end is connected to ground.  One end of the NO pad is connected to the pin, and the other end is connected to power.

To connect it to ground

1. Put a 0603 0 ohm resistor in the pad and don't bridge the NO pad.

To connect it to 3.3V with filtering

1. Put the appropriate capacitor on the pad (if you need multiple, you can stack the capacitors).

2. Apply a solder blob to the NO pad to close it. Now the pin is connected to power with a capacitor to ground.

To pull it down

1. Put an appropriate resistor on the pad

To pull it up

1. (challenging) Bridge the NO pad with a 0603 resistor.
