Suggestions/Decision matrix #2

Hey, first off: Thanks a lot for these boards! They are a great reference for newcomers, me included. I especially like the explanations of design decisions and the clean schematics.

That said, can you offer some advice on when to use which design? I roughly understand how they work, but I can't really say if I should use a TP4056 based board, one with a MCP73831 or one of the all-in-one chips like the IP5306. Are newer boards just better?

Another nice addition would be some kind of checklist on which ones need protected cells and which one doesn't. I think most of these boards need protected ones, but it's difficult to say if some of the chips include protection.

If you need some use cases, here are mine:

Some results from my understanding:

  1. https://github.com/wagiminator/Power-Boards/tree/master/LiPo_Charger_LS_TP4056 is for unregulated LiPo output
  2. https://github.com/wagiminator/Power-Boards/tree/master/LiPo_Power_Board_FP6277 is an extension of that with boost to stable 5V
  3. https://github.com/wagiminator/Power-Boards/tree/master/LiPo_Power_Board_FP6298 is the same, just smaller power output?
  4. https://github.com/wagiminator/Power-Boards/tree/master/LiPo_Power_Board_IP5306 has the same result, but fewer parts. Needs a button press and >50mA to stay on.

If I find the time, maybe I'll do that. Until then, your checklist looks correct so far!
