Well made and good looking board; exactly as described. Arrived fast and well packed.
I have installed an AliExpress ESP32S and LV7829 stepper drivers, they simply plugged in and worked; initial software load went horribly awry due to me shortcutting stuff and corrupting the index file I uploaded then fighting that instead of going to sleep. Following morning I started by erasing the flash on the ESP32 using esptool; and then following the instructions linked above from scratch I arrived at a working box with a local access point half an hr later.. :-)
Software is still evolving, plenty usable right now, with more to come of course. Only thing I miss is 'Go To Zero' buttons for the axes; but these are normally done via macros so it's not an issue. Connectivity via the serial/USB works as normal for GRBL, and I even telnetted to it successfully. I have not tried the bluetooth features; I left them disabled in source since it's not in my roadmap.
