  • “The Leonardo, by the way, is much lower than I expected. It goes to show that issues with the way the Leonardo’s programming was implemented - the less-than-stellar robustness when programming and all the inconsistencies it brings with existing code and Libraries - outweigh the extra features and lower price. Long live the UNO!”

    Where could I learn more about the above? When I design and build something that someone other than me is going to modify the software for, I’ve been using the ATmega32U4 and programming in the Leonardo bootloader so they can easily modify and update the code. I use the U4 because it saves me a bit of room and effort by not needing an additional USB chip. Not being an Arduiono expert by any means, I assumed the U4 was the best choice for these reasons. Should I be considering a 328 and USB chip?

  • Except that…. BVSD had four days off…. but in reality, only the first two were for rain. The second two (Monday and Tuesday) were because most of the BVSD school buses were being used to evacuate the town of Lions. Hey Spark Fun, thanks for the Redboard starter kit!!! It is sure nice to feel appreciated, but now that I’m back at work (and n+16 days behind…) I’m not sure when I’ll get a chance to play with it…

  • Looks like the github links above need updating… for example, I believe the home page should be:

  • Does everyone have blue eyes, or are you guys Digitally Enhanced?

  • I don’t remember exactly, but it couldn’t have been much more than ¼ Amp (running the demo software), or my power supply current limit would have kicked in. So that gives you an order of magnitude answer… They were also brighter than I expected. A quick google shows this web page: Which implies 60mA per LED; that would be 1.2A for all of them all on.

  • Well, looking under a magnifying glass I can just make out on the top of the PCB “SJ-1515ICRGB” and googling turns up: Hopefully the pinout is the same…

  • I just picked mine up, only to find out that there isn’t even a pinout for this product… There are 4 wires between LEDs (Red, Green Blue White) but 3 pin connectors on each end. To make things more confusing, the white wire “T"s to the connector and just a bare wire on each end. Any thoughts?

    I have not used them, but some people have thought their prices seemed a bit high. Download their simple software, CAD it up, it gives you a price quote, click “order” and away you go…<br />

  • I’m surprised SparkFun is doing it again, after all the negative comments from kill-joy sour-pusses…<br />
    <br />
    Last year I purposely didn’t try to get in on the free day, because I feel fortunate enough that I can buy what I need. After reading some comments by people who were going to try to get something that they couldn’t other wise afford, I thought I’d make more room for them. But heck, the $10 credit for each year you have been a customer, I’ll jump on that, since it appears that not taking advantage of that doesn’t make more $ available for others who might need it more :-)<br />

    Thanks again Spark Fun!<br />

  • I agree with Quazar; jumpers to connect the LEDs in series would make this more convenient. I’m not sure why Sparkfun bothered to post a schematic and not board dimensions; the schematic is just (3) LEDs :-) But locations of the mounting holes would be very nice so I won’t have to measure and assume I did a good enough job…

No public wish lists :(
