Retired RETIRED

This product has been retired from our catalog and is no longer for sale.

This page is made available for those looking for datasheets and the simply curious. Please refer to the description to see if a replacement part is available.

Replacement: None. We are no longer carrying the refurbished Chumby parts. This page is for reference only.

Description: Need parts for your Chumby? Need Chumby parts for another project? We now carry a full selection of Chumby parts for repairing your Chumby, or for various other projects. These parts are all refurbished, but are fully functional and will be drop-in replacements for your Chumby. We may not have specifications or additional information regarding these parts. They are meant to be replacements and are not necessarily intended for building a Chumby for scratch. Feel free to play with them assuming this limited information.

For sale here is the Chumby One WiFi module. Believe it or not, but this can be used as a WiFi adapter when plugged into a USB port on a Windows computer! Use this for a cheap WiFi adapter, replacement part, or a really lousy paperweight. Refer to the teardown for more details regarding the replacement part.

  • I bought this RT73 dongle thinking it would work in my Chumby Hacker Board (V1), but when I plug it into the USB it just makes the system freeze up. Also can’t boot with the dongle installed.
    Adafruit claims the Hacker Board is RT73-ready, so why doesn’t this work?

    • I found this page of Ralink RT73 drivers, so was able to get the RT73 dongle running under WinXP!

      Actually, it fired up without a hitch. Ralink provides a nice little utility (RaUI) for managing it too (instead of using Windows WiFi manager). Temperature-wise, the metal cage gets a little warm, but not excessively hot as described above.
      Now if it would only run on my Chumby Hacker Board.

  • Anyone else tried this with a V1 (not Beta) Chumby hacker board? It seems to hang mine.

    • Never mind… I had to slosh some drivers around to undo some earlier chages.

  • Does anyone know the approximate range of this module in clear line of sight outdoors? Assuming the other end is strong (high power router).
    I’m worried the PCB antenna won’t be good enough.
    Thanks

  • I have mine plugged into the Chumby Hacker Board and it seems to get pretty warm, the Ralink chip reads about 145-150 degrees F.
    Is this normal?

    • I have the same wifi card (bought it in store, it’s the inside of a TP-LINK dongle, the cheapest they had). I opened the dongle and the chip was indeed quite hot. I tried to measure it but my thermometer does not fit it exactly, but got around 65 degrees celcius.

    • I haven’t measured the temp yet, but running on a 5.0V bench supply with a meter, it shows 0.23A without the card, and 0.46A after I plug it in. There is probably a way to cut the XMIT power down, which is probably worth looking for since I’ll be running off battery.

    • Sounds too hot. Talk with techsupport@sparkfun.com.

  • Could this be used with an Arduino?

    • oops - wrong thread

    • Potentially, but we would not be able to help you figure out how to make the thing work with Ardunio. That would be cool though, a little snooping around the interenets, there may be some information/datasheets out there to help you on your way.
