Arduino Uno R4 minima is already widely available. Will there be a grblhal firmware for R4 minima? It is very interesting because it can use the CNC Shield Protoner.

If someone writes a driver for it then yes. I am not going to do so because it is a rather slow MCU with limited GPIO. And the pro Eclipse based development tools are not free.

It is very interesting because it can use the CNC Shield Protoner.

Some STM32F4xx boards (Nucleo-64) can as well. Significantly faster MCUs and more GPIO pins that are accessible...
FYI The STM32F4xx grblHAL driver is my main platform so most developments emerges from it.
