 Bigger Bigger  Smaller Smaller  Reset Reset

Is there any smaller/ better way to add ICSP pins to a small project? I am working with SMD and I would really like to keep the project as small as possible and DIP pins for ISP are pretty big and the SMD pins take even more space. I know I can simply create my own connector but I was wondering if there is anything out there that is standardized for SMD projects to keep the programming connection small and out of the way.

Thanks!

pogo pins are usually what are used in the real world

you install the pins in a fixture (just drill holes in something they press fit in) to line up with pads you have provided on the pcb, press the pcb down and contact is made with the spring loaded pogo pins

Try ZH line of JST connectors.
1.5mm pitch, SMT or thruhole.
Then just use an adapter for the ICSP programmer.

The thru holes end up narrower due to not having side wings to help secure them on the board.
10.5mm vs 12mm width needed.

These are 2 eagle libraries I created for vertical headers (if I grabbed the correct files).

Another advantage of thru hole - you can put the connectors on the bottom of the board, mount the SMT parts on the other side, and free up a lot board space.
This particular board has a part that needs heatsinking, the mechanical engineer has the casing that goes underneath all set up so the hot part mounts against the case.

This board has a 6-pin 1.5mm  SMT, you can see the legs that stick out and one of the mounting ears on side.
Also seen are 2 pin and 4 pin thru hole parts. The thru hole crystal makes for a good size comparison.
