It’s blue! It’s skinny! It’s the Arduino Pro! SparkFun’s minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader in a super-sleek form factor that will fit easily into your next small project.

Arduino Pro does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. We recommend first time Arduino users start with the Uno R3. It’s a great board that will get you up and running quickly. The Arduino Pro series is meant for users that understand the limitations of this lack of connectors and USB off board.

To keep things affordable and low profile, we’ve chosen to make the DC power jack footprint available, but not to populate it. We recommend running the board with a LiPo battery for better portability. Also, to keep the cost low, we made changes like using all SMD components and switching to a two layer PCB.

This board connects directly to the FTDI Basic Breakout board and supports auto-reset. The Arduino Pro also works with the FTDI cable but the FTDI cable does not bring out the DTR pin so the auto-reset feature will not work. In this latest version of the Arduino Pro we’ve also moved the FTDI headers back just a skoach so that the pins don’t hang over the edge of the board. We’ve also populated it with a sturdier power selection switch.

Lovely product, low ROI
Size: 4.2 Fl Oz (Pack of 1)
The cream is lovely, not greasy, low odor, and beautifully hydrating. However, being quite the frugal customer, I cannot, in good conscientious, pay the cost per ounce.

Update: Chemical smell?
Edit: Something seems to be different with the current version. Why does "pure tallow, beeswax, and raw honey" smell (and taste!) like cheap perfume? Ick. Good luck getting that scent out of your brain. And what the heck is it? I don't know why they changed it but it unfortunately wasn't an improvement. It's too bad. It made a great foot balm. Pretty moisturizing and the size and form factor made it easy to apply. Hope it comes back the way it was. _______ This has great/safe ingredients. It's huge. And the company seems legit so I tried it. I've given it a go and it's okay but it seems like the proportions would need to be adjusted to be more of a balm. It's good… just a little too greasy. This feels more like I just put my tallow moisturizer on my lips instead. I get that from Fancy Farm and I guess I'm going to have to stock up on theirs if I don't find something else here that has that consistency. (And no seed oils!) Lip balm needs staying power or it just becomes a nuisance.

Finally, a non-toxic chapstick!
So I typically make my own products at home using beef tallow. But I was in dire need of chapstick, and just didn't have any time or energy to do it, so I came across this brand on Amazon and had to try. I love it! Not only is it HUGE, but it is unscented, it's glides on perfectly and my lips feel super moisturized for hours. As with all tallow products, you have to be super careful about letting this stuff sit in the heat. So if you were planning on keeping it in your purse or car, it'll definitely turn into a ooey gooey mess. I keep mine in my nightstand in an air-conditioned room, and even then it gets a bit too warm on our hot 103F Summer days. Nevertheless, I recommend to those who are looking for a non-toxic chapstick that super moisturizing.
