ESP32 with accu

[wulf@goldmail.de]

Hello,

I‘m searching for an ESP32 within step up converter and charching adapter. I want to use an 3,7V accu and the output-voltage has to be 5V.
I‘ve allteady realized it with an single charching adapter and a mini step up converter, but unfortunately this take to much area/space in my project. I know that‘s possible to get some hardware with both things in one but before I will use this I try to find a smarter solution.
Can somebody explain me wich ESP32 I have to use in wich way to go on with my project? If you have another idea for charching accu with usb-c and using an ESP32 for wled with about 40 leds (5V) in a way wich is as small as possible - please share you knowledge.

Thanks!

Wulf

I think your only solution is to make a custom board. Many ESP32 boards have built-in charging systems but none come with a built-in boost converter.
