  • I think the hookup guide is misleading. I changed the jumper to 3.3V. It tells you to select 3.3V 8Mhz micro pro in the Arduino IDE. But that bricked my board. Also my reset button wasn't working outta the box. I couldn't figure out why the reset trick wasn't resetting the processor. I manually jumpered the reset and that worked but couldn't get it to hit bootloader mode correctly still. Then I ran the BAT file the instructions point you to but that never worked either. I finally cleaned the reset button and it started working again. Then I could do the double click and recover the board. I changed the setting back to 5V 16Mhz and the sketch loads and runs fine now. Very frustrating process to get through. Hopefully this helps someone else.

  • The only thing I could find was 3-7 meters. Depending on how good the lens is they can see 30 meters but I'm not sure on this one. It's made by Hanse and they don't have any better datasheet on their site. info

  • I realize it drives a single output. Here's my method. Assuming in dot mode it only drives one line at a time based on the Analog input. You tie all the 7 segment LED legs together that make up a 1 and tie that to the lowest LED input. Then tie all segments that make up a 2 together and tie that to the next LED input. Then when it hits that voltage it sinks current through all those segments lighting up the correct number.

  • You could use one of these to drive a 1 digit display and get 0 to 9 displayed as the analog voltage increases. That would be a pretty cool and easy digital display for a throttle control, temp range etc.. without a microcontroller.

  • Read the page a little more closely. Top left corner is a table of contents which lists the page example sketch

  • Anyone know where to find a SIM Card Breakout. The difference being it's a little simcard with wire extension. I want to use the board here at sparkfun to create a sim card extension cable. I haven't had much success finding one.

  • It does not support audio. I suggest the WT32 module by Bluegiga. I've used it and very easy to get a project going. http://www.mouser.com/ProductDetail/Bluegiga-Technologies/WT32-A-AI4/?qs=bzgYiMiT8X1PoaLuPkujPLxdARVg6opL

  • I know my mom said if you can't say anything nice don't say it at all....BUT seriously!? That caption won?!!? That was probably the lamest, not funny, unoriginal one out there

  • It's made to charge a 1 cell Lithium poly battery. 4.2V is the max voltage you want a 1 cell to reach as you're charging it. 3.7V is the nominal voltage of the cell. Fully charged it will sit at 4.2V. Once you start pulling current from it the voltage will sag to 4.1V down to 3.1ish then it's dead and needs to be recharged. So yes it's suitable.

  • You guys should put a HUGE spotlight on the roof and everytime a gift code is given away it blasts a laser beam to space. That way we can see how well its going from afar...

No public wish lists :(
