- I knew I was doing something wrong with power management; you know, if you look at many popular "maker" websites you often find such solutions which are good for many projects but when start biting back they do it strong. I like your suggestion of using an ESP module, I think I'll consider the ESP8266 for this (It seems the ESP32 is too much for my project). About the 3), can you point to some resources for examples or some component name? (so I can buy the right parts. Same for the 5, so I won't buy the wrong regulator). Thanks a lot, great answerDamien Pirsy– Damien Pirsy2019-08-13 15:06:05 +00:00Commented Aug 13, 2019 at 15:06
- Any P-channel MOSFET that has a threshold voltage between 0V and -2V would do the job. You don't need much current handling capacity. I usually work with surface mount SOT-23 devices, so any part number I would have to hand would probably not be suitable for you.Majenko– Majenko2019-08-13 15:08:06 +00:00Commented Aug 13, 2019 at 15:08
- 1As for a regulator, there's LM2596 based adjustable modules readily available on eBay (be sure to adjust the voltage properly ;) ) - but again, any part numbers that I use would probably not be suitable for you since they would be small surface mount ones.Majenko– Majenko2019-08-13 15:09:31 +00:00Commented Aug 13, 2019 at 15:09
- I think I'll follow your advices and look into ESP8266 modules. NodeMCU, Weimos D1, any favorite? Anyway, thanks a lot for the answer!Damien Pirsy– Damien Pirsy2019-08-14 07:49:36 +00:00Commented Aug 14, 2019 at 7:49
- If you replace the Arduino with an ESP32 don't use an ESP32 development board, use the module! All development boards still use a lot of power even in deep sleep.

How to Edit
- Correct minor typos or mistakes
- Clarify meaning without changing it
- Add related resources or links
- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
- create code fences with backticks ` or tildes ~ ```
like so
``` - add language identifier to highlight code ```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible) <https://example.com>[example](https://example.com)<a href="https://example.com">example</a>
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. arduino-uno), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
