  • The early SD card form factor concept/prototype was promising; the final product looks disappointing. I should have expected it to be ruined in (over)design-by-committee and marketing, as is the way with huge corporations like Intel. A shame…

    Regardless, thank you SFE for carrying and supporting this. :)

  • It’s a Honeywell IC.

  • Just received one of these; first impression is positive. Four screws would have been nice (as others have mentioned), or even having them as an optional add-on at extra cost. I’m curious, what plastic is this made of?

  • Suggestion for board revision: silkscreen pinout on both sides. You’re already paying for “sparkfun.com” on the second side, so why not make more use of it? Actually, this suggestion applies to many other SFE boards…

  • Just noticed something on the label; this is RoHS compliant as it contains no peanut butter. (Lead is Pb, not PB!) One tip: brush on some flux before reworking this solder. Great stuff.

  • Using a straight-edge and sharp utility knife, just score through a column of holes, on both sides, and snap along the edge of a table. Repeated scoring makes the snapping easier and edge cleaner. You can also sand the edges smooth, if you like, but wear respiratory protection!

  • USB 1.x/2.0 micro-B connectors are too delicate and annoying to align, in my humble opinion.

  • Most things that people are doing with Arduino do not rely on 20ppm precision timing where 100ppm would fail. For people who want long term precise timekeeping we suggest going with a TCXO (temperature compensation crystal oscillator) - but you would know if you needed that. — Lady Ada

    If you require precise timing, you should design your own boards.

  • Glad to see that you’ve populated the ISP header on this revision. The only possible improvement I can see now would be adding a 3.3V / 5V core logic selector switch. Anyway, nice work, SFE!

  • I have several of these boards, populated with both M & F connectors. The only annoyance I’ve found with this breakout, is that the pinout silkscreen is on the wrong side if populated with a DB9M (DE-9 M, but let’s not get into that…) and straight male headers on opposing sides. I say the wrong side, because if you stick it into a breadboard, the silkscreen is on the side you can’t see!

    Of course, there are a couple of solutions to this; only one is satisfactory, in my view. First, you could populate with the connectors on the same side and hang it off the side of a breadboard with the power rails removed. Second, you can use 90° headers, but then the board’s sticking way out of the plane of the breadboard and causing all sorts of trouble. Finally, SFE could simply add a pinout silkscreen on the other side of the board—which they’re paying to have silkscreened anyway with “sparkfun.com!”

    So, SFE, how about a ‘non-gendered breadboard-friendly’ rev. 2 breakout with pinouts printed on both sides (when your “378 in stock” run down)? Pretty please?

No public wish lists :(
