Step 5 Long and Winding Ribbon Cable

Making the various header connections depicted on an AVR Device Connection Sheet is best accomplished with a fistful of jumper wires. A 20-position socket with ribbon cable can reduce the drudgery of soldering 1-position socket receptacles to both ends of 20 jumpers. Using ribbon cable is optional. If you elect to use ribbon cable, cut the cable to a length of approximately 7 inches.

Regardless of your choice, you will need to make one jumper for each header/ZIF connection that is cited on the applicable AVR Device Connection Sheet.

Hi popsci thanks for the help making sense of what needed doing! For what it's worth, I did mine with pcb-mount sockets instead of flying leads; see pictures. (NB: these are for Atmega168, which has a slightly different pinout, but intended to show the principle.)

I also like the perf board. I made mine with 2 40 position receptacles and the small one. The digikey part is A32967-ND for the ones I bought.

I really like your idea of making the "cable" on a perfboard. Very elegant.
