  • …so then I woke up and this dude here is totally using my bedrooms soldering station. And my red stapler that was right here is totally gonzo!

  • The easier to solder connectors are not necessarily a good thing. I’ve had several micro-USB connectors snap off of 5V Pro Micros while attaching a USB cable, lifting traces in the process and generally being a big pain to repair. Maybe the solder pads to the left and right of the connector should be made a little larger to give the connector a little more footing on the board.

  • Never thought I’d openly say this, but I’ve got knob envy. :-P

  • 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.

  • Actually, I did a little Googling and found someone trying to use two Wii Nunchuks together on a single Arduino (Nunchuks are hardcoded with 1 I2C address, so this is a similar problem to what I’m facing). It was suggested that it might be possible to run one using Wire.h and the other using a software-serial library. Now that I think of it though, maybe I could gut a Nunchuk to use as the third gyro ; that might be the simplest solution here.

    My project is a biped robot. I’m putting one gyro in the body and one in each leg. This way I can measure the angle of each leg in relation to the body as they are moved.

  • Is it possible to assign 3 of these different I2C addresses, then have one Arduino read the values of those 3 boards to compare?

    I see that its address is 0x68 by default and can be changed to 0x69 by pulling AD0 high, but what if I need to read a third board too?

  • This is one of the most useful kit’s I’ve bought. My only criticism (as others have mentioned) is that the standoffs are about ¼" too short to be safely usable.

  • A big puff of smoke from the regulator and one of its caps just answered my question. :( As is my unfortunate way, I accidentally sent 16.8V to RAW. The Pro Micro does still work perfectly if I feed a nice safe 5V into VCC, but its own regulator ist kaput!

  • Can anyone share what the trick to installing the drivers for Windows 7 x64 is?

    I’ve got “SparkFun ProMicro (COM8)” showing up in device manager, along with another USB Input Device. I’ve selected COM8 and Arduino Leonardo in Arduino 1.0, but when I try and upload a sketch I don’t get the popup trying to install the Leonardo driver. It eventually gives the ‘not in sync’ error.

    Help!?

    Edit: Nevermind, I got it working. I think my problem was an FTDI adapter that I also had plugged in. Maybe the hardware ID’s conflicted or something but when I removed the FTDI adapter Windows installed the drivers without a problem.

    Thanks for another great gadget SparkFun!

  • So with the beefy regulator and diode and fuse in place, if I was to accidentally feed something over 16v into this (let’s say 24v) would it just shutdown, or would magic smoke come out?

No public wish lists :(
