  • I finally built this kit and its just not working for me… I checked to see if I get 5v at the wire holes, and I do….

    Is there something else I can try?

    I’ll admit this was a bit challenging for me but I think I made all the connections….HELP!

  • No matter how you look at it, you may have four but mine is BIGGER!

  • I just realized the Max7219 work with a common cathode..not the common anode of this display :-(
    ..but at least I answered my own question! :-)

  • Can someone tell me if I were to combine a lower 2mW with a 50mW Xbee the sort of range I could expect? (sorry Im a newb!)

  • Has anyone ever used this with the Max7219 chip and an Arduino? I’m trying to get this to work using the LedControl-library but am having problems. I’m not really sure where to start!!

No public wish lists :(
