  • I'm disappointed that technical support will be moving to the forums. One of the strengths I felt that SparkFun had over Adafruit was that SparkFun provided high-quality, individual tech support over email, while Adafruit required people to go to their forums, where questions often went unanswered or weren't answered well.

  • This looks cool, but I wish it exposed more than 4 GPIOs, especially since the underlying processor seems to have so many.

  • Yeah, I've run into trouble hand-soldering them. I can hand-solder the four signal pins with a little bit of care, but I can't figure out how to solder the two mounting pins, which are necessary to hold the connector in place. The mounting pins are recessed inside the plastic housing, and there is very little exposed area, so I can't manage to get a soldering iron in there to heat the mounting pins without melting the housing.

  • Are these connectors available in a through-hole version?

  • In another comment below, it was mentioned that there exists a $10 programmer. (Haven't tried it myself, though.)

  • From the schematic, it looks like the Variable Load Kit does not supply power to the LCD backlight. Does this make the LCD hard to read?

  • It appears that the latest batch of readers that SparkFun is now shipping have the 1.7.1 firmware preinstalled. (Specifically,

  • I received my antenna a few days ago. I just wanted to point out that all the shiny mounting hardware shown in the fifth photo is not actually included.

    Does anyone know where I can buy a mounting bracket like the one shown in the picture? Has anyone had success mounting this to anything, and can you share your experiences? Thanks!

  • If you're on Windows, you should be able to use the Universal Reader Assistant software from ThingMagic to update the firmware. If you don't have access to a Windows machine, you could try the tmr-firmware command-line utility which is part of my Haskell binding for Mercury API. Either way, you'll need a USB-to-serial converter to connect the board to your computer.

  • Yes, I've tried the on-board antenna at full power. I would say it's in the ballpark of the advertised "1 to 2 feet", although it's not consistent. I've sometimes had it read tags 2 or maybe even 3 feet away, but other times I've had it not read a tag less than a foot away. So don't take it too literally, but I would say it's a correct description.

No public wish lists :(
