What is it?

ICSP pogo pin adapter for programming PCBs with a header pinout, but no populated pins.

Why did you make it?

Other options were sold out, shipped from overseas, or weren't quite what I wanted.

The design align the ICSP header up directly with the pins it's programming. So you don't have to figure out an offset, or how things correspond at 90º or what have you. It's as if headers were physically soldered onto the board and you're placing the ICSP header on it.

Additionally, the design is very small, allowing it to get into tight spaces.

Finally, if you choose to assemble this yourself, a 3D-printed jig is available for sale, or you can print it yourself via the file available here. I'd recommend printing it yourself if you have a 3D-printer, and would especially recommend soldering things up yourself. It's not too hard, and I'm charging a significant fee for what will certainly be poor solder joints as I'm honestly not that good at it.

Notes

Solder jig coloring may vary, and is printed for functionality, not beauty. Also, there's an option for me to solder it. This will be functional, but likely not very pretty.

Option available to include an ATtiny breakout board, seen here. Does not include the actual ATtiny, which is a bit of a bummer these days, and probably contributes to them not selling very well.
