NESPI solderless mod:



  • Hi everyone,

    I'm trying to find a solution for the NESPI case that has a hard reset and hard shutdown buttons. I've found lots of tutorials that are recommending soldering stuff, which i have never done and don't want to. I have found a set of buttons and leds but i am not sure if they would work in a Pie. Do you guys think that these will work?

  • @cgeyik I don't have the NESPI case, but looking at the photo of that item, it looks like there is an assumption that the wires from the switches lead to header pins that are side-by-side. That might not be the case in reality. Often, the switches share a common ground and the other pole on the switch needs to go to a GPIO pin that might not be sitting next to a ground pin.

    So, could you make it work? Maybe, but you would still be adding wires--best soldered. Then there is the question about whether the switches would work. I suppose with glue, anything can be made to work, but how are you going to get the existing switches out of the way? By replacing the whole button board with something scratch built instead? This seems like it would be trickier than just learning to do the soldering.

    Besides, most of the guides include using resistors where appropriate to avoid noise-triggered switching. How would you go about following those steps without solder using this part?



  • @caver01 I plan on using pins 5 and 6 for shutdown and boot, pins 9 and 11 for the 'universal exit' button. I hope i can clue the NESPI buttons to the buttons on the switches. I don't know what noise-triggered switching is. I'm learning everything as i go. If someone thinks that this is definitely not going to work, please let me know.



  • Learn to solder. It's fun and easy!



  • @cgeyik Well, maybe it will work. You have a pinout that might. What can it hurt? If it doesn't work, you can always still learn to solder for a plan B.



  • @cgeyik I think learning to solder would be the easiest option. As the case comes, the power/reset are hard wired into the power in and all current flows through both buttons. I just cut the traces to the switches, which isolated them from the power circuit and allows them to be used for other purposes, and soldered power in directly to the pins that go to the pi. So eventually you’ll have to solder something to the power in. I did a whole rundown of my build in a couple threads.
