Electronics and anti-static foam

Hi!

Probably a very noob question, but… I want to run some Arduino shields separate from the Arduino, and want to protect the pins on the shields. Is it 100% safe to power up the shields while the pins are placed in anti-static foam?

I guess you could see what happens if you use your multimeter, and set it on resistance measurements. Measure the resistance between pairs of points on the foam block.

If you get relatively low resistance readings, then it wouldn't be a good idea to power up your arduino with the pins embedded in the foam. If your foam is electrically conductive, then not a good idea to power up the arduino in that situation.

On the other hand, if the foam is measured to have relatively high resistance, or appears to be an electrical insulator...... then it should be ok to power up the arduino in that case.
