With the recent surge in Omicron cases, shipping may be slower than stated times. We are working to build, ship and respond to everything as quickly as possible. Please see all COVID-19 updates here. Thank you for your continued support.

  • Note you should remeber to attach the antenna before plugging the module into the board, since the connector is on the lower side. Also note that this baby talks by default at 115200 and does not seem to autobaud, so use this baud rate if you are not seeing expected feedback.

  • I would welcome any thoughts on the SM5100B versus the ADH8066. I have a GM862-QUAD which I used for GPS transmission, and love it because in includes a GPS receiver, but now I need to construct something equivalent. It looks like the ADH8066 might allow for a slightly more compact design. The help guide at http://www.sparkfun.com/pages/wireless_guide suggest the only difference is U.FL vs SMA, but I am sure there are other variations.

  • Some of the codes that are given as hex in the documentation (e.g. 0x18) are actually decimal (e.g. 18). I forget which, but it might be all of them. It's easy to verify.

  • AT 5 volts it works, but the contrast when viewed straight-on is too low to be usable (the characters are almost invisible). Viewed at a 45 degree angle, you can read stuff which makes it acceptable for testing at 5v, but not actual deployment.
    The lack of support for newlines (CR/LF) by the backpack is a huge flaw.

  • Any luck driving it with only a 5V or 5.5V supply (presumably at reduced brightness)?

  • I made some notes on using the ML-7, especially with Apple OS X, on this page: http://www.dudek.org/blog/164 since OS X drivers are not included or present on the vendor site. Re. the other comment, about the cables as stand-alone products, they cable seems similar to some times of cable based on the FDTI chipset.

  • Well, 5 volts all the way works fine.

No public wish lists :(
