Funny, you should bring this up. A month ago i just finished a VoIP phone project for a client. I did try the RPI way first. You can use one of these to help with the audio in/out for testing your code, then later use the IC in there on your own board. https://www.amazon.com/gp/product/B001MSS6CS/re...

bumped into this today and thought of you. would this work for you? it has enough output current for the ESP32. https://www.dfrobot.com/product-1712.html?tracking=5ae99700e0477&utm_source=DFRobot_Newsletter&utm_campaign=c7965b3172-EMAIL_CAMPAIGN_2018_05_02&utm_medium=email&utm_term=0_0633b8d2f9-c796...

ok cool. So do we just keep checking that link to see if things changed, of is there a better way to know when an update is posted so we can try it ?

Getting Started Documentation is here: https://docs.espressif.com/projects/esp ... index.html I don't know if it's me or what, but those instructions are clear as mud to me. IMHO, you should have a single step by step install without all these links jumping around to areas for the old way. Just mak...

Having no idea what your building and your power requirements is going to make it hard to just say "get this"

it could be that your new voltage converter, is not capable of suplying enough current. When the WI-Fi turns on it going to spike.

The link provided was not in English, so I was unable to get any information on it as far as what the "out +/-" pins output for voltage. But from the photo of the board it looks like your battery should be connected to the "battery" terminals and not the "output" terminals. 4.2v is probably to low f...

From the link you gave there are batter +/- connections and output +/- connections. Why would you connect the battery to the 5v output?

but when I plug my TP4056 card

Would be more helpful if you previded a link to what "TP4056 card" your talking about, and how you have it wired to your ESP32.

IMHO, you have to much emphasis on using JTAG to program the device. If not using JTAG, there should be no JTAG warning after flashing each time. There is another issue where it does not follow the download board rate.
