EDU Circuit Overlay

David Betz

I just bought a few of the new Parallax EDU Circuit Overlay boards (https://www.parallax.com/product/32999) and they are quite nice. I had been using an Activity Board to test code that runs on the Propeller Memory Card and had it wired up to the breadboard on that board. Yes, I know I could have plugged it directly into the P0-P15 header but I didn't want to have to add code to set the power pins appropriately to power the board. Anyway, my breadboard circuit worked fine and I decided to move it to one of my new EDU Circuit Overlay boards. Everything went pretty well except for one minor point. I moved the wires I had used on the breadboard over to the EDU module but when I soldered them in the insulation on the wires melted and shrunk a bit exposing some bare wire. Now this didn't really matter because none of the wires were close enough to touch each other but it isn't as nice looking as I had hoped. Are there wires that have insulation that melts at a higher temperature that would be better to use with the EDU modules than the wire that is typically used for breadboards? I know about Teflon wire but was hoping to use something that was a little easier to work with. Any suggestions?

Thanks,
David

I just use PEFT insulated wire for most soldered stuff. It has the advantage of the insulation burning off while soldering, and only where soldering (thus it does not shrink elsewhere). Though you can not strip it, though if soldering why worry about that (ok you can use a flame to strip it).

Silicone insulated wire has always worked for me. More expensive, but the silicone has a higher melting temperature than ordinary plastic or rubber insulation.
