There were still two pink Stemteras left in the SparkFun Retail Emporium (inside to the right of their front lobby) when I stopped by this afternoon, Friday, June 23, 2017.
I compared the black, orange, and blue Stemteras side-by-side for legibility and they were just as I thought from the large images on the product pages. The lettering on the white one seems the most legible. The blue lettering on the black and blue ones was a little hard to read (not as much contrast between the lettering and background colors). The red lettering on the orange one was a little hard to read, but there is very little red lettering anyway. The two pink ones left were still in their factory sealed anti-static packaging, so I did not want to disturb them and did not compare them. (The SparkFun staff person forgot to bring a white one for me to compare, but I decided not to ask him to make a second trip.)
I elected to pick up the black one I had ordered earlier anyway; it’s somewhat unique (won’t get lost among my many other white solderless breadboards) and the black color might make it easier to see dimly lit LEDs I add to the breadboard. Maybe I’ll review the black one after playing with it a while.
Noticed by me also. This incarnation DEV-13975 of the RedBoard does not appear to be included in the table of boards listed in Sparkfun’s Arduino Buying Guide linked sparkfun.com/arduino_guide at the end of this product description, even though the older RedBoard DEV-12757 is listed at the very top of that table as retired.

Nate, I’m guessing you meant January 21st, not March 21st (although it was claimed to be a march). I will refrain from any political comments regarding this event. This pink Arduino-embedded breadboard, however, also reminds me of seeing pink graphing calculators. I often find pink goods among clearance merchandise, even when more conventional colors are still being sold. And my old dorm room at CU Boulder was puke pink until we quickly repainted it off-white.
I noticed technical comments about STEMTera were on the black version page at
https://www.sparkfun.com/products/14082 and none at the white version page at
I wish there was more technical information available on this particular implementation of an Arduino Uno. I couldn’t find any on the stemtera.com product page, just ordering and promotion information, and only a little at the Kickstarter page. It’s not even fully clear if a 16U2 or a 32U2 is used in the one available here.
I’ll probably order a white one eventually, as that’s what I’m used to and is probably most legible, although the black one might be interesting (easier to see lit LEDs?). I don’t know if a transparent one (see Kickstarter and stemtera.com product pages) would be all that useful in this case, except for solderless breadboard absolute novices, which actually might be a significant market (related to the education market).
I spent lots of time with Legos as a child in the 1960’s, before they had a reliable electric motor system or other accessories (I had the old white motor block with transparent cover, before the later blue motor blobk and battery box with reversible on/off switch).
I suspect this STEMTera product might soon become standard in Electrical Engineering introductory labs, and maybe others (junior/middle/senior high schools? physics? mechanical engineering? aerospace?). My introductory embedded systems EE class at UC Denver uses Arduino Uno/Mega and solderless breadboards. I had a thought or two of a similar product last year, but after looking though the STEMTera Kickstarter updates, I see there is an awful lot that goes into actual product development, especially concerning plastic injection molding and related production and testing issues.
I, too, wish the microcontrollers had been socketed, although soldering them on keeps the initial cost down and increases reliability (at least until a chip is blown). The first microcomputer company I worked for, the digital group in Denver (aka Denver donkeys), socketed all DIP ICs.
As you said, this looks really intriguing! Thank you for supporting development and distribution of this new product.

Will Local Pickup (with no shipping charges, but state and local sales tax charged) still be a shipping option for Almost Free Day? Will there be a minimum order size implemented for Almost Free Day orders? Will we have to do those awful Captchas to participate? I live in Boulder and SparkFun is a short drive away; I have a project I need to finish.
