I can’t find the other black cube that sticks onto the arduino. Everything is still working I think so I’m wondering if I really need the other one and if so how can I get another
Are you maybe talking about the heat sinks that stick into the motor control shield? Those are pretty important, the chips that they protect are subject to thermal damage without the heat sink. These are very similar, should do the trick.
Those are heatinks and are important… find it and stick it back on. I ziptied mine to the board because they kept falling off
If we forgot to put them in the box let me know and I’ll send you some for free right away!
