Making a Reset Switch for your Raspberry Pi Model B+ “RUN” pads #piday #raspberrypi @Raspberry_Pi
Are you looking to embed your Raspberry Pi into the belly of a custom enclosure or prop where it will be awkward to remove? You can take advantage of instructions for connecting a reset button or switch to the pair of pads on the top left corner of the board marked “RUN” by following tutorials for the P6 headers on the Model B (previous model). For comparison, please consider the two detail shots (from the Adafruit B+ update guide) below to see where the P6 pads moved between the Model B and Model B+.
One of the changes on the Rev 2 Raspberry Pi board, which I haven’t seen anybody write about yet, (apart from Eben in his original announcement) is the addition of two holes for a header at P6. These were added to enable a reset facility. Shorting those two pins together resets the processor. This was too good an opportunity for my curious mind to pass up, so I decided to add a 2 pin header there and try it out….
…Of course, you don’t need to install a “proper” reset switch. A jumper would do, or even a paperclip. You don’t really even need to put a header on. You could short across the holes with your paperclip (it’s only a momentary connection). I’m not saying you should, but you could. It’s obviously the “preferred way” to use a header. I did consider putting a 2 pin socket there instead – to avoid accidental reboots – but the decision was made for me when I found the ready made reset switch. 🙂

These are almost perfect, you just have to use some needle nose pliers to bend the leads inwards and down. They fit in the small space.
