When will we see a revision to this board to switch power to battery when wall power is removed?

I connected the board to my PI and the battery shows that is 100% but the UPS function is not working when I unplug the power to the PI HAT

any help?

Thanks,

Hi, Could you please give some extra infromation about the functionality of "dtoverlay=gpio-poweroff,gpio_pin=22" I tried to activate it, but it doesn't seem to have any influence on the behaviour of the board....

What is/should actuallly happen?

Hey, t seems that it should NOT be gpio_pin=22 but gpiopin=13 or gpiopin=6 i.e. no underscore as the manual for this dtoverlay seems to be inconsistent, and the pin numbering is the BCM numbering not in WiringPi numbering nor in physical pin numbering... and it seems that one needs to solder on the board... COuld you please comment on that?

Best regards

This thing drained my LIPO beyond it's recovery when there was a long power outage.

Thought I have a safe shoutdown implemented at 40% charge. It seem to not have a cut off to stop draining battery even in standby mode. I am using additional ESP which runs only on power to switch the pi back on.

I tried to register on raspberrypiwiki.com but it failed to allow me to register. Said no permissions.

Is there someone here who can help configure this board? It reboots when I disconnect wall power instead of switching to the battery. I have the Auto-UPS turned on and it still does not switch.

I have the same problem. It fails to be a UPS as removal of electricity 5v 3a input interupts the PI and makes it reboot

Same issues here. When the external power is removed, the power to Pi is shut off for a second and then the Pi boots up again. This defeats the purpose of the UPS!

This is the same problem I find. It does not matter if the switch is set to "Auto" or "UPS" the board will not provide power to the Pi when external power is removed. I had high hopes for this board as it was a V2, I expected it would have all the bugs worked out. I guess not, it is still crap. I do not know if this comes from bad manufacturing quality control, or just poor board design, but if you are here trying to decide if you want to buy one; I highly recommend not getting one of these.

What size JST connector did you go with? There are several options, want to make sure I order the right battery.

Hi. There is an error on the "raspberry pi ups hat 2 size" picture. I believe we should read 5.6 cm instead of 5.1 cm.

What's the height of the board (each side and total)?

Is there a way to hack it to support LiFePO batteries?

You might provide some dimensions for the board?
