I am currently working on a single PCB PiPod. This new version of the PiPod will have a higher resolution display(2.2" 320x240), a bigger battery and a safe shutdown button. I have designed three small modules for the new parts that I want to use on this version these are currently being produced by @oshpark . While I am waiting on the PCB's and parts to arrive I am working on the final version that I want to verify with these small modules. These modules are also a great way to practice using my new reflow station before using it on the PiPod ;)
This power button circuit will make the Raspberry pi boot while the pi is booting it will turn on a GPIO that turns on the booster circuit and a LED to indicate that the power button can be released.
