News - Announcing the ProtoSnap … | about 11 months ago
That’s what this is for: http://www.flickr.com/photos/rsbohn/302298301
Product DEV-10508 | about a year ago
No problem if you do everything in octal. Then you can use 8 for zero and 9 for enter!
Product DEV-09003 | about 3 years ago
Took several tries but I got the USB attached and the whole thing is working! Now I need a signal generator…
Product DEV-09003 | about 3 years ago
Mine arrived today! I’m guessing that the USB mini-B header is an alternate way to power the board. The silkscreen for C1 has a white ‘–’ looking mark on the lead that ties into the positive line, and I’m a little concerned that R2 will interfere with the 6 pin ICSP port (yeah, I plan to use it!)
Other than that it looks like a good, clean board. I’ll have to post some photos after I melt some solder.
Tutorial - Better PCBs in Eagle | about 3 years ago
Thanks for running these tutorials. They really help.
I put a date code in the bottom copper layer, but the BatchPCB robot rejected the board. I’ve changed it to a larger graphical date code (boxes for year, circles for board version). Perhaps a macro could encode the date in some standard (in the community) representation?
Also, how do you set the default trace width? These 8 mil traces seem a little small, but I don’t want to replace every individual trace segment.
Thanks again! SparkFun rocks!

Nice little development board for 8 pin AVR chips. The 10Mhz oscillator is not connected. If you want to use it you have to bridge two pads on the bottom. But for chips with internal oscillators just leave it as is. I might pull it off and use it in a different project.
The board has a +5V bus and 0V bus along the card edges. Each pin on the chip is available on a pad, but you might have to search for PB3 and PB4.
I plug the ICSP into my Arduino, pulling the +5V and ground using the edge busses, and find I can run SPI to the 8 pin chip.
This is a good board to get started with 8 pin AVR. Be sure to get a few Tiny13 chips when you order. Some extra headers for the board will also come in handy.

Simple to assemble. See the photos at

Now to build something on it!
