I had assumed that the current rash of these app-configurable devices on e.g. Amazon (Sonicake Pocket Master, Soran Tiny Stomp, Lekato ME-05, M-VAVE Pocket Amp, Strich Pipe Tones etc.), with the Sonicake the progenitor as I understand it, were all based on some sort of hardware platform at least somewhat quite close to this sort of profile, and they all appear to be running one OEM vendor’s software, but this is interesting indeed because of NAM 2.0.
I am in the market for one of these, perhaps I should build this for fun.

  They all use underpowered DSP chips from yesteryear. ESP32 is a great platform, and P4 is doing even better. I have a prototype running 2 A2-full profiles, along with 10 other effect blocks, on a P4.
  I believe we are starting the age of personalized hardware, and Waveshare & co are doing a great job at bringing affordable, multi-purpose devices our way.
  Would love to hear your experiences if you try out this build.

    Hi! Great project.
    OK so I have a little J&D USB-C guitar cable thing:

    Any idea if this will work? (Notably working on my Mac but not my second generation iPad Pro, which sees it but is confused)

    Thank you! I am surprised it doesn't work with iPad Pro. They don't ship to Germany, otherwise I'd buy one and try. If you have an ESP32-S3 device, I can help you with it if it doesn't work.

    Oh I found one on Amazon.de and ordered. Will let you know :)

    Sorry — I should have added that there is a variation of this device that (allegedly) does work with the iPad Pro, so if you have time to amend your order…

    I don't know why this one would work and the other not, but my guess will be that this one has a chip that doesn't offer up a disconnected output device as well (which would be my totally uneducated guess as to why my iPad hates the other cable and the Mac, which has switchable output devices, doesn't)
    There was an ESP32 board I wanted to try (below) but it looks like it's a 1.8" sibling of the one you are using so maybe I'll just track down the one you're using.
