breadboardpcb
I want to do some prototyping with a microcontroller on a breadboard.
The microcontroller won't fit in the breadboard holes because it is square and small, and has many pins I won't be using.
I would like to connect the pins of the microcontroller to the breadboard via the standard jumper cables (22 AWG) to a female socket. I've tried to find them, with no luck.
Perhaps someone here could point me in the right direction?
Thanks
The pins of a 40-pin ZIF will have the same spacing as a 40-pin DIP. The issues to watch out for are: (1) some ZIF sockets have pins which require larger holes than would be required for most sockets, and (2) nearly all ZIF sockets are wider or longer than ordinary sockets; many are significantly longer. If you wish to solder a ZIF socket directly into a board, you should leave room for this. My normal preference, however, is to solder an "ordinary" socket into the board and plug a ZIF socket into that. If you take that approach, it may be possible for the ZIF socket to overhang some low-clearance components.
The datasheet doesn't show the pin header but assuming it is like this
You can get a female to male dupont cable
Your board uses the 100mil pin header style so the dupont wire I show can be used.
Just do a search for dupont cable male to female, you can find it almost anywhere.

I would recommend getting a breakout board for the chip. You can either get a breakout board for the specific chip that contains some support components, or you can get a generic breakout board that provides a DIP form factor pinout for all of the chip pins. For a 100-TQFP, this should not be terribly difficult to find.
