I originally ordered a 16x32 RGB display from Adafruit when they were first offered a few months ago. It came with a positve and negative post to screw wires onto for power (as shown in the Adafruit tutorial).
I ordered another 16x32 RGB display as I also ordered their FPGA and got it working but wanted to do more with these displays.
I noticed the new 16x32 RGB display was a little bit different. It has a snap in connector for (2) +5vdc and (2) Grounds and not the 2 metal screw posts as shown in the tutorial. It also came with a snap in cable. I am using a cut power connector (as shown in the tutorial) to connect this to the 10A 5vdc power supply I bought all from Adafruit. I also bought some longer IDC cables from EBAY as the ones that come with it are way too short. I was able to rig up the new cable between what I had using the cut power connector but it's a bit messy with different connectors.
However, what I really liked was the new display also came with 4 very strong magnetic screw posts. Great idea!
Can I buy more of these magnetic screw posts for my orginal display? I really like these but only having 4 between 2 displays makes it difficult. I currently have them magnetically mounted in a 32x32 form on a non-stick round cake pan for working purposes.
Let me know!!! I will probably buy more displays and great Adafruit products. Also I love the "premium" wires they have compared to the slightly cheaper solderless breadboard bundled wires. Great ideas are flowing at Adafruit.
