Pogo Pin Lobot

Lobot with Pogo Pins

For programming boards that don't have the ICSP header pins installed.

Same Lobot PCB as before. Pogo pins installed in the ICSP header instead of the Pro Micro footprint. Cheap Tiny AVR ISP programmer board installed.

Spring pressure makes contact with the unpopulated (no pin header installed) ICSP pads on the PCB.

The pins are delicate. I store this in an Altoids tin. More info on the pogo pins can be found in the Lobot post.

The pogo pins are soldered to the top PCB (bottom in this picture). This has to be done with the two PCBs assembled. I used a piece of kapton tape to keep the pins from falling out while soldering. Solder the back row first without the front row in place, there isn't a lot of room to work.

The pins are not soldered at all to the bottom PCB (top in this picture).
