  • Did someone in the engineering department verify that this module is safe and actually capable of delivering 1A at 5V? Before purchasing bought 250+ of them? I bet not. The lack of UL certification and the price point says a lot…

  • In the same week you released this LED array board, Adafruit released a series of 9x16 LED arrays, available in multiple colors, for $3 less. They also have an optional driver board for $6 and FAR better code support than what is presented here. It’s very unfair to make this comparison I know, but sometimes the truth hurts. I haven’t seen any exciting new products from Sparkfun in months. It’s like the “spark” to innovate is gone and you all are just skating along on your current catalog. This is very sad to me, I miss checking out new products every Friday and making an order for the following weekend’s projects.

    So what happened? What changed behind the scenes?

    Notice that engagement on your blog posts has dropped to almost zero, except for the “controversial” ones or giveaways. Perhaps others feel the same way I do. I post this in the hopes that the old, exciting Sparkfun can come back some day. :)

  • 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.

No public wish lists :(
