  • so i got mine now, and tested it with a M5 nut. As someone else have said allready there is no standard threading on the rods as there is 2mm pitch or something. To bad. Sparkfun, please get one with standard threading. M6 have 1mm threads, use that! ;)

  • This probably tells a little about how much we Sparkfun customers demand more stepper motors and especially motors that makes it easier to interface directly with other elements as rods, and other mechanical things without having to use a coupling.

  • I will meassure and test mine with a regular m5 rod when it arrives in a few weeks

  • I allready ordered myself one of these.
    Is it possible to take the included shaft out of the motor and insert a regular M5 threaded rod? This would be so brilliant for alot of robot applications when you dont want that coupling between the shaft and the threaded rod.

  • Could you please recalculate the estimated holding torque for the new stepper motors listed to give out the same data as the first one you had in stock for some time.
    the old one reads Holding Torque : 2.3kgcm
    Whats The kg
    cm on the new ones.

  • Love it!

  • I love this. Actually bought 2 last friday. But im trying to work out how many of the Digital pins are used for the ethernet part, and how many are left for me to do stuff with.
    Is it right that digital pin 0-11 and analog 0-5 is open for fun?

  • Yes.
    Just wired it up like this.
    Pin 13 SCK
    Pin 12 MISO
    Pin 11 MOSI
    Pin 8 SS
    Also i had to change a line in the example code to be able to set the time.
    SPI.setDataMode(SPI_MODE3); // Mode1 didnt work

  • Now all you need to do is to remember to check on Twitter to see if your plant needs water..
    I built something similar, but my project is actually watering the plant when it drops below the desired threshold. Maybe the next version of this pcb could have an io out so you could connect to an mosfet with a waterpump for watering as well.

No public wish lists :(
