Does anyone know of a supplier that produces a 'pro' version of the Arduino Mega 2560.
What I mean by 'pro' is a board with similar layout and functionality to the Mega, but without the headers, the power connector or the USB connector.
I'm getting to the end of a project based on the Mega, and I want to make several copies for permanent installation. I guess I'm looking for a Mega version of the Arduino Mini or Arduino Pro Mini.
Are you asking for something like this?
You provide regulated power, a crystal and two capacitors on the crystal pins, and a 6 pin header and you can program this with an AVRISP II or many other programmers. This guy guves you a $12 chip, a $1 board, and his soldering expertise for $25 which seeems like a fair enough markup if you can't solder these yourself. You can get this board and do it yourself if you want.
To do the soldering yourself:
