I just ordered via eBay what appears to be the same TPL5110 board, but without the Adafruit logo. I suspect they're all made at the same place. I'm hoping this board will behave as expected and will validate my perception there's a bad batch from Adafruit. It will take a few weeks for the order to arrive. I'm not meaning to deride Adafruit in any way....just trying to get a board that works as expected.

Adafruit boards are made at Adafruit in NYC. The 5110 is a pretty simple chip so I can't see much variation in design.

So....board finally arrives from China. I soldered it up and it pretty much acts the same, albeit with a slightly different look due to a different LED. No power is passed to the Feather.

I'm throwing in the towel...I haven't a clue as to what's happening and I've invested so much time.

Have you tried a TPL5110 board from Adafruit?

I've tried 3 of them. They acted the same way, which is why I ordered one via eBay (from China) to see if it was simply a bad batch from Adafruit.

Bummer. All I can say for sure is that it works when I wired it up exactly like you did with board from years ago and a new one.

I totally don't understand. I tried today with a Particle Argon micro-controller to see if that would make any difference...none. I'm not one to give up, but I haven't a clue as to where to go next. All I really wanted was to be able to power the micro from battery for multiple years. I couldn't get low enough deep sleep current, so I turned to the TPL5110. In any case, I appreciate your continued feedback and suggestions!

I'm truly baffled. If you want, contact me directly (See linktr.ee/dastels) and we'll arrange to send you what's working for me.

Tried to DM you via Mastodon. I'm totally new to it, so I'm not sure if I did it correctly.

dastels -- Did you receive the TPL5110 boards I sent you a month ago? I've tried messaging you via Mastodon, but have heard nothing.

I've gotten and replied to your mastodon messages... still haven't gotten the hang of it yet I guess. They seem to work as you described (no big surprise there), but I haven't gotten beyond that yet. Did you get the message I sent this morning on Mastodon?

Did not get any messages from you via Mastodon. I'm not thrilled with that service, but it could be my fault.

Yeah. I've seen messages from you, and have replied to all of them.
