We’ve just revved our open-source ATtiny2313 breakout boards to version 1.1.
There are a couple of nice improvements for the new version. First, we made the board single sided to match our original ATmegaxx8 board– this means that it’s relatively easy to print out the layer separations and make your own at home, if you like to etch your own boards. We also changed around the configuration of the prototyping areas, making it so that you can now fit up to two DIP-8 packages, breadboard style, on the board.
This is an open-source project; the designs are released the GPL, GFDL, and CC-BY-SA licenses.
You can download the design files for version 1.1 of the card here(592 kB .ZIP file). This is a ZIP archive that contains the full schematic diagram (PDF format), PCB layout, and layer separations, both as PDF and gerber.
And as usual, if you’d like to take the easy way out and just pick up a few of these, we can help you out with that too.
