Instead of using a breadboard, I'm looking for a ready ready-made piece of hardware that does the same. Has a ZIF socket so that I can easily remove the ATMEGA after programming. Maybe has a LED so that I can quickly check if everything worked. Something like that.
I am sure the Chinese must have build something like that I just can't find it on eBay - because I'm not sure what exactly so search for. Could you guys maybe give me a link to an item on eBay?
Not what I was looking for I already know those types of boards.
They (1) have a crystal (i intend to use the internal clock) and (2) they don't have an USB interface -> I have to deal with JTAG & programmers again.
Adafruit makes a programming shield with ZIF socket that you plug onto an Uno for programming.
Or you can wire one up. I did one recently to have a ZIF socket to use with a Programmer, and use a FTDI Basic to give it power and check the serial interface.
ZIF sockets, protoboard, 100nF caps, 10K pullup resistor, and crystal & 22pF caps for full speed if desired can be had inexpensively from www.dipmicro.com
ZIF sockets have wide pins, I soldered a machine socket to the bottom of mine so I could wirewrap to it.
'328s don't support JTAG. You need a Programmer to change the fuses and load in the bootloader if you are using one, or the sketch if not, so something has to act as a Programmer no matter what. I put an ICSP header on all my boards so I can program them in place.
I even offer a standalone Programmer: http://www.crossroadsfencing.com/BobuinoRev17/
I'm doing the same sort of thing, and just bought a ZIF socket, soldered it to perboard, and connected pins and sockets along both sides. Only cost about 6 bucks in total; may not be as pretty as some of those shields, but it works well enough.
