And if you’re inclined to make any small-quantity custom circuit boards, I’ve used both PCBs.io and OshPark, and I’d highly recommend both. I’ve only submitted my own design with OshPark, but I’ve ordered a shared design from PCBs.io and both turned out great.
For reference, OshPark’s pricing is/was $5 per square inch for THREE copies of your board, including through-plated holes, solder mask, silk screen labels, gold-plated contacts, custom shapes, everything. No setup fees, no shipping charges; you submit your files online and the boards arrive in the mail between 1-2 weeks later.
(Note: I don’t think Fritzing has a way to create custom board shapes; only rectangles)
