Were you going for a Pro Mini with a Li-Po connection or a USB stick? i’m confused. Because SURELY your engineers would design a USB stick around the 32U4 with USB built in, designed to operate on 5V USB, with a much cheaper BOM.

Have you done a cost-benefit analysis on this? I take it you have done the math, and that accounting for every resistor in the building makes up for the lost day of productivity, and all of the stuff that gets damaged or misplaced while being handled and manually counted.

Yeah that third Monday of every January is really tricky. It just appears out of nowhere!
You will be shipping on MLK day?

Hey baby, let me Spark some Fun into your life.

If you check the schematic and datasheet, you’ll note that the 32.768 kHz crystal is connected to the XOSC32 pins. This is a secondary input specifically for 32kHz oscillators, as the name implies. Ideally an external crystal for the primary clock would be connected to the XOSC inputs. However, I’m pretty sure they couldn’t do that for compatibility reasons with the Arduino Zero. The Zero uses these pins as D2 and D5. So it’s Arduino’s fault, not Sparkfun’s. Assuming you think it’s a problem. Is it a problem? Meh. The FLL/PLL on the Atmel SAM chips isn’t very good anyway in my experience.

Yup. This is a really nice board, and it absolutely has a place in the market. A low-cost alternative to the Arduino Zero that is a great introduction to the ARM world. But you guys/gals missed the boat on how to sell it. Atmel’s ARM chips are not the next versions of AVRs. ARM is a completely different world, but one that advanced hobbyists really need to be moving toward. Also, by selling it without headers, you just made it a breakout. That limits the audience that will consider it. Why not take your awesome board, put headers on it, populate the DC jack, think of a good name, figure out how to describe it correctly, and really make an impact in the hobbyist ARM world?

Good article, thanks for your work and research.
This seems like overkill for an 8-bit AVR though. Going down the road of more and more libraries and layers of abstraction, you eventually end up with something that is more complicated than the original starting point. Configuring a timer and ISR in Atmel Studio is no more complicated-looking than the code shown above, and actually teaches the programmer what the AVR is doing behind the scenes. It’s the difference between having control over the device, and relying on someone else’s abstraction to gain the appearance of control.
You might also considering doing one of these articles on ARM devices and showing off the SysTick timer.

I was expecting some comic relief at the end, but jeez that was kinda sad.
Thanks Rob! Best of luck with your future plans!

The new format is probably as good as the old format, but it’s a change. And you know how people don’t like change. It was also bad timing in that it came at the start of a very slow period for new products. Seems like it’s been months now. It’s not just you guys, I haven’t placed a big order with any of my favorite online vendors in a quite a while. RPi and wearables seems so popular right know, but I just have zero interest in those. I don’t need 10 different RPi cases, a hundred different ways to light up an RGB led, or yet another microcontroller breakout. (cough Adafruit) I used to look forward to you guys having new sensor breakouts, interesting kits, or other little electronics bits that I could build projects around. But that just hasn’t been happening lately, so I’ve moved on to other things.
As for the cellular board, did it take longer than expected (like a year longer?) to get this one finished up and released? I’m not really sure where a $70 2G cellular shield fits into the market right now. I’m sure it works very well and it looks ok, but yeeeeah………
