    One thing that is worth noting in the mentorship section is that not only learn from having mentors, but also being a mentor to others. I’m still a fairly young engineer, but I’ve had a few engineers straight out of college work around me, and answering their questions actually forces you to improve your knowledge base quite a bit.

    How does this display perform without the backlight? Is it still somewhat readable? I’m hoping to use this as a display on a project both for its small package and the fact that it’s fairly low power.

    Just curious, will there be a buss bar version of this board be sold at some point?

    In case I’m using the wrong adjectives (I do that sometimes): I’m talking about the long power busses that are on larger bread boards. Those are separate pieces on the larger breadboards, so I’m guessing that there would be a buss option for this form factor.

    That’s actually a fairly good description of how they’re used 99% of the time.

    A bit more details: The difference between a P and an N is that an N-channel fet will turn on (aka, conduct) when a voltage greater than the drain&source voltages is applied to the gate, while a P-channel fet will turn on when a voltage less than the drain&source voltage is applied to the gate. Now, in your example, if you wanted to switch something off from the high side (the +5V side), you would use a P-Fet. To turn on the device, connect the gate of the FET to ground. To turn off the device, connect the gate to +5V. This gets a bit trickier when it comes to switching something that needs a higher voltage than what your microcontroller is using, but that can be solved by using an N-fet to invert, then connect it to a P-fet in succession.

    Hope that helps.

    I’m hoping there are plans to use this on the Sparkfun coffee mugs.

    So let me get this straight, I can go with 10cents/message anywhere on the planet (SPOT) or I can go with 10cents/message within cell phone range (T-Mobile prepaid)?

    Just to clarify, that’s page 22 of the hardware application notes.

  • Product KIT-11068 | about 2 years ago

    Does anyone know if the connectors will be sold separately at some point? Also, will the schematics be posted soon?

  • Product DEV-11021 | about 2 years ago

    What is the purpose of the new I2C pins? According to the schematic, they are the same node as the original I2C pins. Is there a planned branch in the hardware where the A4 and A5 pins will no longer support I2C?

    Also, does anyone know of any example code for the keyboard emulation using the 16U2?

    I’m also thinking of using this for backpacking/outdoorsy stuff.
    What exactly is the “hard-board backing”? I’m hoping to glue some kind of tether to it so I can hang it off the back of my pack when I’m walking around.

No public wish lists :(
