  • I would caution that the output from these is extremely low. I purchased them to use with a raspberry pi but have also tested in my regular desktop machine. While they do work and are recognized the volume level needed to make them pick up anything at all makes them useless. If I put my face to them and yell I get a sound file with almost the same volume as from the built in computer microphone from 3 feet away speaking softly. Unless there is the same thing wrong with both of them that I purchased but given Member #796889’s comment below I think that is just how these are. If anyone has the secret firmware setting or something to make these function like any other usb microphone please let me know. I can’t imagine that in their current state they would be good for anything.

  • I recall reading a piece of speculation that it was lack of room to expand while charging that caused the batteries inside those samsung phones to catch fire. It might not be a good idea to embed that part directly in the resin if thats actually true that they need a tiny bit of space. Would it be enough to wrap it in a mm or so of foam tape so that it keeps a little room to expand once embedded?

  • Is there a more recent Fritzing part payout for this? I believe the one that I’ve got in the most recent version of Fritzing labled as V. 4 is incorrect. It’s one pin spacing too small for these radios. As you can see here:


    the far 4 pins are skipping the first hold that they should go into and the last one is going into the pad I actually created for an antenna output. Measured like this:


    It falls short of the 40mm I measure from end to end with my calipers.

    It’s possible my Fritzing doesn’t have the most recent libraries? It says v. 4 but when I just downloaded the latest things from your repository on github that radio wasn’t in it, though it’s listed as sparkfun in fritzing?

  • Why are there export restrictions when it was imported in the first place? I know... silly question, just ignore me. I love these, they are awesome.

  • I just used it this evening under Mavericks to configure some cards for a friends setup and it still works just fine. Sorry, dont know why you were having trouble. But it’s good to have multiple tools available. Thats what happens when a company actually publishes their protocols, I wish more would do so.

  • I am having no luck getting this on the network here at all. I have the previous version of the cell breakout board that Sparkfun sold based on the ADH8066 module and that works great with the same SIM and the same antenna and the same power supply. But when those 3 things are moved to the new board I never get joined on the network. The signal strength is always 0,99 and I never get the +SIND:11 message that would indicate that I’ve joined. SBAND is set to 8 as indicated, but I’ve also set it to 7 since someone in the comments above suggested that and when that didn’t work I worked my way through them all from 0 to 10. Rebooting the board each time and never getting an SIND:11 message. The rest of the communication to the host works fine, all the SIM commands work fine, but I cannot actually join the network. Lastly I’ve now twice desoldered, cleaned and restripped the antenna cable and re-soldered it but that hasn’t made any difference either. Lastly I just sacrificed another spare pigtail and soldered it in place on the board but I still can’t get a SIND:11 or do anything on the network.

    Any suggestions for a next step? Are there init commands other than the SBAND that I’m somehow overlooking in the docs? I can’t set the COPS or anything until I actually join the network as far as I can tell.

  • ah, nevermind, I see the cellular category is not under wireless and there already is the “SM5100B” board. I will look at that.

  • Will there be a replacement for the ADH8066? Do we know anything about it yet? I see the wireless section here doesn’t even have a cellular category anymore.

  • I do all my development on a Mac as well. If you need to configure Wiznet cards from your Mac you can do that with http://www.planetarygear.org/2012/06/wiznet-configurator-for-mac-v2.html

  • question on the power supply capabilities of this board. Will the board provide enough current to power the "basic 16x2" LCD at 3.3v? Or should I get the 5v version and power it directly from the charger outputs. But then the next question is there going to be a problem between the 3volt logic pins on the processor and the 5v logic on the display if I do that? Thank you!
