[quote=106064]Ive been using my extra samsung cables and they work fine directly plugging into the pi with a 2A adapter. I think it has to do something with the ciruit itself.

Well oddly enough, the USB cables seem to have worked! I hooked it up briefly last night with them, and I saw a brief warning square while it was first booting up, but never again after that. This was with the keyboard and ethernet plugged in I put it through it’s paces a little bit and never saw the warning, even faintly.

This weekend I’m going to reattach the LED and see if that causes enough of a voltage drop to trigger the warning.

I haven’t gotten the replacement board yet, but for now I’m satisfied.

[quote=105990]So I tried my 3A micro usb charger with the USB version of the shutdown circuit and still get a low power indication.

Okay at least that’s one thing ruled out.

I haven’t gotten the replacement circuit yet but I was making an order at Monoprice so I threw in a couple of these, which have thicker power wires. We’ll see if they help.

Just got a reply from Mausberry, he thinks it’s likely the USB cable I’m using, but he was kind enough to send me another one just in case. I asked him to send the direct-plug variant this time, eliminating one usb cable link in the chain. I probably should have ordered that one all along.

I’d be interested to know how it goes with the 30w power supply though, grizzlema.

Yeah, I did that initially too. Being a noob, I mistook GPIO 23 for PIN 23. I have the board connected to the right pins, and it functions to shut down the pi just fine. Very strange, perhaps I got a bad board.
