There probably is if you look hard enough. Closest thing I can think of is the MKS-DLC32 motor control boards that are generally used in 3D printers and laser engravers. You can buy just the board and reprogram it. They just run grbl with serial and web interfaces anyway and have an arduino bootloader.

yea, they tend to want to take in tmc2209s or other low-power stepper driver chips.. my use case is to drive bigger (3A+) motors with external stepper drivers. I'd also like to easily use 24v sensors and stuff (hence level shifting and not just mosfets..)

something like the teknic clear core but esp32-based.
