Without a battery installed, it won’t keep the time during shipping. (Battery sold separately)

Did either of you guys consider having a look at the datasheet for the fingerprint module? I know this is a radical concept for the “modern” engineer, but you just should give it a try!

What are the sizes of the mounting holes? I can’t find it anywhere in the data sheet.

Kinda strange because they do have that information in the product brief, section 10, Mechanical Dimensions – but apparently didn’t re-use it for the datasheet (which should be authoritative, but that...

I don’t see why not- I have a script running in Python that can send an e-mail via Gmail, and Python runs just fine on the pcDuino.

It’s unfortunate that this breakout board doesn’t have logic level converters on it so it can be used with +5V microcontrollers. I’ll not be purchasing this board therefore.

Just got mine but I’m seeing some strange behavior: I have two batteries. One is LiPo 7.4v 1000mAh and the other is NiCd 7.2v 1600mAh. I was using the NiCd for about 15 minutes (I have the Wild Thumper...

@Mike Grusin: Thank you, as per your suggestions I was able to change the baud rate at which this device communicates before de-soldering it.

Is it possible to generate a negative voltage output with this? I’d like to give it +12V input and have the sketch vary the output between -12V and +12V.

This is undoubtedly one of the worst microcontrollers ever to be sold by Sparkfun. Perhaps not Sparkfun’s fault: simple negligence when there are too many Arduinos to track the actual performance and...

The description says “GPIO are 3.3V but 5V tolerant”. Is that supposed to say “GPIO are 3.3V OR 5V tolerant”?

Well, that shouldn’t matter much. Most of the time you are putting a Lego axle through a round hole, so it can be in any orientation. Only if you are trying to mate with a beam with a ‘+’ is the...
