    No — last weekend I started making the old PCB compatible with the new workflow. The latest phoenix branch has a desktop app that controls both the Mini and the old PCB. The firmware auto-detects which board you're building for based on the build target:

    • idf.py set-target esp32 → PCB v1

    • idf.py set-target esp32s3 → PCB v2
    Pinouts and drivers are configured automatically — no manual defines needed. No new PCB required.

    The goal for the new PCB (v2) is faster step rates, more precise timing, and Ethernet control — but the old PCB is still supported.

    Important caveat: this is all purely in testing right now. I have not attempted to run it on the actual rig yet — so far it's only communicating between the ESP32 and the desktop app (serial handshake, geometry config, etc.). I intend to do real hardware testing on the rig later this month. As well ive got my first order of parts for the new pcb to test a single motor out with.
