    The complexity of the dedicated system and the price of its application have nothing to do with the use of some simple MCU in this application.

    And I would first think about what I need, and then choose the layout that best suits my needs. Why do you think there are literally thousands of microcontrollers on the market, sometimes with different details? There is no one-size-fits-all solution.
    The combination of ESP with the MCU makes sense, as written by col. @tronics , the only question is whether the use of such a simple MCU as in the subject brings a lot. IMHO, there should be a processor with much more extensive peripherals. The core of this processor is secondary, because ESP has enough power, unfortunately it lacks peripherals, which in the embedded world is a very significant disadvantage.

When it comes to AVR, when I had to program them, ATmega3208 and ATXmega16D4 were the best. I would choose some ADUCM361 Analog Devices (hobby EKG, EEG, holter and others), but I don't know myself - everyone does what they can.
    It is advertised as a microcontroller. MICRO CONTROLLER! Now, in terms of peripherals, it is not much better than the AT89C51! It is terribly poor. A friend writes about dedicated systems, okay, if I wanted to make a 16-channel dimmer, I would probably take some PCA, or TLC, or something else. But if I just wanted more different things, the functionality of which I could change from the menu, website or whatever? Exactly. The topic concerns an attempt to use such a duo - perhaps an unfortunate example, because - as tmf noted - weakly expanding (one uart we talk to ESP, one i2c, one spi, a few timers and logic level mismatch), something new, at 3.3V with a better "repertoire" it would be even more fun, but at this point we are entering the ESP32 price range, which may not support everything in hardware, but has definitely more peripherals and can afford to charge the core up to 100% for the application, because it supports WiFi / BT is the second, dedicated.

    Speaking of audio, here is an interesting album: https://www.elektroda.pl/rtvforum/topic3514250.html
    in which ESP has been surrounded by systems that ensure audio playback and recording.
    I was surprised by the lack of MEMS microphones, but apparently electret microphones are sufficient.

    ESP8266 + VS1053 and internet radio are nice, no need to combine. Regular ESP clocked at 160MHz is enough, I made an internet radio clock radio on it, I recommend it. It supports most Polish radio stations such as RMF, ZET and others.

    Greetings


    Out of curiosity whether that's what you're done on or something else :) ?

    or maybe on this?

    I use ESP as a microcontroller in a project with no wifi ... So this is definitely a microcontroller and it's fast for its price.

    Yyyy but it's a mystery or how, if so it's ok and if not, I'll be happy to know what and I'll be happy :)

    There is no secret, I only answered your closed question ;)
    I used the library of our compatriot https://github.com/baldram/ESP_VS1053_Library with my modifications. Plus, a Nextion touchscreen lcd and a light sensor to automatically dim / brighten the lcd. The clock is an imitated flip display, such an old school. Time taken from the internet from ime server via ntp. When I come back from the delegation, I will throw photos ;)

    You write that this connection makes no sense. Have you thought about people who build various types of projects based on arduino uno? It is enough to replace UNO with the duo UNO ESP and their prototypes gain access to the Internet without any additional modifications.

    Let me refresh the topic a bit. I decided to give the ESP32 a chance and order the ESPDUINO-32. The price of $ 6 with shipping encourages you to experiment.
    Information about this plate was already available published on the electrode.

    Not yet, but it should be before Christmas.

    She came a little later: /
    Tested and recommended for "Arduinists" as an alternative to Uno.

    One note: the pins work in 3V3 logic, not 5V. You have to remember this, especially when using overlays, which were primarily designed for the Uno.
