Was versucht diese Schaltung zu tun? Ist es PTT? Eine Seite der Schaltung ist ein Empfänger und die andere Seite ist der Sender?

It is a draft to power an ESP32 in an Ikea Bluetooth player. Since the device is equipped with a battery, ESP32 should also be turned off when the player is off. To do this, a switched 3.3V, which can be found on the PCB of the radio, drives the 14.4V of the battery through the Mosfet. The 14.4V are then regulated to 5V for the ESP32 via a BuckConverter. And actually the circuit should not be public ;)

But it doesn't matter if it is public. Thanks for the explanation. I see the required functionality

I had no idea IKEA offered Bluetooth players. Q. Why put an esp32 in a device that has Bluetooth... I assume you have an esp32 with both WiFi & Bluetooth. I also guess that you are not trying to stream audio via the ESP32 and so this must be intended for some form of remote control via WiFi?

That's not my player. A friend of mine is using it. He needs the ESP32 for RMS support via the following project: https://github.com/philippe44/SqueezeAMP The Name of the Hardware is Ikea Eneby.
