  • Product PRT-00114 | about 3 years ago

    I like these little guys so much I got a couple. They’re actually capable of delivering at least 2-3 times the current that the PTC limits them to. I have a project that needs ~300mA and the PTC was kicking in, so I soldered a short jumper across it. I also added a heat sink to the voltage regulator as it was getting pretty warm on its own at that point (I’m using these power supplies along with the 9V 650mA regulated wall warts sold here. Like those, too.)
    The PTC is a great feature though, especially for beginners who are more likely to wire something wrong. Now that I’ve said that, watch me go fry something ;-/
    Gotta love the pilot light too. I never forget where I put my project any more.

  • Product WRL-09132 | about 3 years ago

    Have to second this one, especially since the product web page says, “The board was conveniently designed to mate directly with Arduino Pro boards and with the FTDI Basic boards for wireless bootloading and USB based configuration."
    I do not think it physically possible for any two of the three boards (Arduino Pro, FTDI Basic, XBee Explorer) to interface directly. It does look to me like the XBee Explorer will interface directly to an Arduino Pro (Mini). Of the three possible combinations of these three boards, one will always require a turnaround adapter.
    I’ll be soldering one up if anyone needs me. But I would change the statement on the web page.

  • Product LCD-09396 | about 3 years ago

    This display has worked well for me! I wish a current schematic were posted, so I’d know what the connections on the edge of the board are. There are 6 pads on the bottom and 10 on the top of the board. Basically right now I’d just like to make the RX, Vcc and GND connections via standard 0.1" headers if available there, but it’d also be nice to know what the rest of the connections are just in case there’s other coolness available.

  • Product COM-10079 | about 3 years ago

    Anxiously awaiting the breakout board!

  • Product SEN-08733 | about 3 years ago

    Does this fit the 3-pin connector on the serial LCD displays, e.g. part no. LCD-09393?
    If so, I’d recommend a note/link to that effect on the LCD pages.

No public wish lists :(
