Re: Tackling Graceful Shutdowns on the GBZ

Yes guys but then why not really do a board that includes both powerboost and mosfets? You could even have nice pads for en low batt and my be even disable?
@Camble Thanks. Understood so far. What about the "reset" button?! Not needed any more with this setup?Camble wrote:Alright, I'll update when I can. In the meantime, I've got a short guide to post in the Hardware section. I want to test @Popcorn's dtoverlay=gpio-poweroff idea with first.
@larsen2011 Yes. The circuit shorts EN to GND on the PowerBoost to keep everything off. After you slide the power switch to off, the JFET keeps the circuit open while the Pi shuts down.

PCBs have already been designed and ordered with the Button/switch controller integrated with the battery charger and boost controller. It is a little bigger than the powerboost to accommodate the extra components. Ill be looking for a couple people to test the boards in the US once they arrive and I have them built. I will write a tutorial on how to wire them up and how to configure Retropie to work with them once I have the proto-boards in house.

Personal funds or is there a preorder thread?prerunnerseth wrote:I'm still working on building up funds to order my first 100 of these boards. Hopefully soon.
personal funds... I need to buy 100 or more for it to make sense... going to be a bit of money up front.Ganreizu wrote:Personal funds or is there a preorder thread?prerunnerseth wrote:I'm still working on building up funds to order my first 100 of these boards. Hopefully soon.
