If you are an electronics hobbyist who develops PCBs, this thingy is for you! As one who designed quite a bunch of PCBs with micro-controllers, I often encounter situations where there is no room for adding a jtag connector, or a connector is needed only once for programming, and hence its a waste of space and parts to mount it just for a single programming sequence. The solution for that is preparing bare touch contacts on the pcb, and use pogo spring pins connector to hold into the pcb and perform the programming. But what happens if we need to do some debugging as well? We can not just hold the connector manually throughout the entire process, we need something to hold it there. This is where the #D printer comes handy!
Apart from printed part to will need: a. M3 screw and nut, b. M5 screw, a washer, and 2 nuts. c. A pogo spring adapter such as this one: http://www.ebay.com/itm/250805614388?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Print the the 2 parts!
If needed, using 3mm and 5mm drill, make sure the screw holes are wide enough.
If you are using the proposed pogo spring adapter, use a utility knife to carve the adapter head do it will fit the holder.
- just look at the attached image for clarity.
