  • Am I correct in assuming that this will NOT work with this battery, since that’s a 3-cell battery, and this is designed for a single-cell battery? Can anyone clarify?

    EDIT: Or maybe I can use that battery with this product, because it’s still 3.7V and the batteries are in parallel?

  • This right here. Someone who knows how to do 3d printing or whatnot get on that (i.e. not me). PLEASE?!

  • Oh, I got it back together. Probably not the easiest way, but it works now.

  • I’m really happy I didn’t order the tilt-pan bracket, having finally seen the note at the bottom of the product description.

    Anyway, for $12 I’m not expecting precision machining, but this thing leaves a lot to be desired. It gets the job done, but required a fair amount of pushing and shoving to get that gear in place. The clutch was also a bit difficult to get on the medium servo, but it does fit. Just be sure you don’t accidentally open the clutch, as it’s only held together with magnets.

    Overall it’s not bad, but I’m waiting for that tilt-pan bracket!

  • I got snazzy box and hacker stickers. No rubber feet (would have been nice, but whatever). Also no anti-stat bag (again, whatever).

  • Yeah, it looks like the LED is present. I’m not sure if it’s backwards or not. It’s really small and I don’t have a magnifying glass (dumb). Other than that the board WAS working well. In my excitement to just get it working, I soldered some wires to the appropriate holes. After that I decided that I’d rather have male pin headers, so I tried desoldering (using wick) the wires and in the process managed to lift the pad off the dir pin. :( Anyway, it still works, but it’s now going to require an ugly looking hack to work properly.

  • Just got mine today. Had it up and running with a PIC18F4550 in about an hour (including solder time). Pretty easy setup.
    I was under the impression that there was supposed to be an LED in one corner of the board. Either that’s been removed in this latest version, or mine doesn’t work. I mean, my board works fine and controls my stepper just fine, but there is no LED to indicate that power has been applied.
