  • Product BOB-09118 | about 2 years ago

    I gave this a try with a 3.3V Arduino Pro Mini. I could reliably transmit serial data at up to 14400 baud. 19200 and above didn’t work, though.

    The 4 Channel Optoisolator DIP worked a bit better – all the way up to 57600 baud, but it requires a couple external resistors to get set up.

  • Product COM-00784 | about 2 years ago

    I tested this out with an 3.3V Arduino Pro Mini, and was able to transmit at up to 57600 baud without problems. As bbotany expected, 115200 didn’t work.

    This works way better than the opto-isolator breakout for transmitting serially. That only worked up to 14400.

  • Product SEN-09418 | about 3 years ago

    I gave this a try. It acts like it’s grounded, but it’s not really reliable. If you touch the board at all, it’ll get confused and think it’s tied to something else.
    Best to just solder a jumper to GND to be safe.

    I’m planning a balloon project with the XTends. Do you have any more info on your antenna setup? Specifically, how your car antenna is mounted / oriented, and perhaps a link to the circularly polarized antenna you used on your payload?

    Why does this have shipping charges?

  • Product SEN-09801 | about 4 years ago

    Ahh, I thought it was -13200 @ 0 C. Much better now. Thanks :).

    Gyros work great. I like the built-in filtering options.
    Heads up – for me it came set to use the alternate I2C address (0x69) instead of the default (0x68).
    Has anyone gotten good data from the temperature sensor? I’m getting values around -16,000, at room temp =/.

  • Product GPS-08975 | about 4 years ago

    PMTK220,200 made the difference for me :-). I wonder why that command isn’t in the list on the PMTK Protocol Reference linked to here…? Weird.
    (For reference, the ‘200’ at the end there means milliseconds between sending data back. default for mine was 1000=1hz)

No public wish lists :(
