AVR ICSP board

thingiverse

I redesigned the sej7278 tray to be compatible with my multi-type ICSP programming breakout board, and I was immediately drawn to its snap-in concept - all I had to do was adjust the board dimensions to make it fit. The breakout board itself has a 20-pin ZIF socket that allows me to program any thru-hole AVR chip with 20 pins or fewer. Two separate 6-pin ICSP headers are used to choose the type of chip, and additional jumpers are included for similar chips with minor variations. I also found it convenient that there are socket pins provided for 3-pin ceramic resonators, allowing me to accommodate chips that have already been programmed with an external resonator. I've included Eagle schematic and board files in the package, so you can create your own breakout boards if needed. If you'd rather have a ready-made unpopulated PC board, I recommend ordering three at a time from oshpark.com - just search for the shared project with the ID C6x84QJX.
