  • San Diego gets no love?

  • In addition to my previous comments, I have found another flaw. There are no provisions for pull-up/pull-down resistors. The A/B RS-485 lines don't make their way to the breadboard so you can't put pull-up/pull-down resistors on easily.
    Also, why a 220 ohm terminating resistor? If you're using Cat-5 isn't the impedance of the twisted pair typically 120 ohm?

  • There should be an assembled picture of this. In my haste to order I didn't realize the break-out was either RJ-45 -OR- 3.5mm screw terminal. The verbiage states "and" not "or".
    Upon receiving it, I realized that the side-pins are the standard .1" header pins mentioned, not for the screw terminal which only mounts if you do not mount the RJ-45 connector.
    It's my fault for not doing enough looking at the schematic/eagle board layout/PCB picture, but a simple picture of the completed PCB would have helped.

No public wish lists :(
