Poweboost 500c wiring

Hey all. So I have the pb500c and a micro lipo. My first build is using the 500c. Can someone confirm how to wire it. I've never used an adafruit power boost before.
From the guide. I will wire the middle pin on the switch to ground. And the left pin to the EN on the 500c.
Can I use any ground on the 500c?(or should I ground it somewhere else?) Also. For power to the pcb will I use to the 5v hole or the bat hole. I assume bat. Sorry if this seems dumb. Just want to confirm first.

Should follow the Adafruit simple lipo wiring mate.
500c:
Battery 5V and GND to circular pins at bottom.
Batt Pin to middle pin on power switch.
GND Pin to main GND on PCB
Right hand pin on power switch to main VCC on PCB

Thanks for that. In the guide it states this, I wasn't really sure what the en pin is for. But looks like I can wire it exactly the same as the micro lipo too? Is there a reason to use the en pin over the batt pin for the switch?
Also. I've wired the battery to where the JST connector is.
Note: if you’re using the powerboost, you want to connect the middle switch pin to ground, and the leftmost switch pin to the EN pin on the powerboost. That way when the enable pin is put to ground (when the switch is to the left), it’ll shut off the power

The enable pin, when it's connected to ground, basically disables the powerboost (it still drains some power from what I understand but it's on the order of microamps). So you can wire up 5v/GND pins straight to the button PCB, and connect the power switch to the EN pin and another ground pin. But you'll want the leftmost two pins of the switch to be hooked up to it, so that when the switch is flipped to the left (i.e, off) it'll put that enable pin to ground. Hope that makes sense.

Yeah, that makes sense to me. I mostly wasn't sure if I needed to use the 5v pin, or the bat pin for main power to the PCB.

I just did this in one of mine so that I could get low battery sensing. Here's the wiring I used:

Pretty much the exact wiring I did. Great diagram. I didn't even think about the low battery sensing. Once I open it up to add the speaker I will add that as well.

So far it's been working great for me - doesn't have the fancy battery level indicator but in all my tests so far it's properly sensed a low battery and cleanly turned itself off.

Sorry if this is a stupid question, but does it save the game before it shuts off? I’m a noob at this and was just wondering if I could lose some progress in games.

Nope - thats what the delay is for, so you can save the game (or save state) before the system shuts down.
