There are many STM32F1 based boards made for Mach3 that can be reprogrammed with grblHAL firmware. Currently I have this one:

DDMACH V5.0

It's based on STM32F105VCT6. Where to begin with? I can easily trace pinout.

Where to begin with? I can easily trace pinout.

Creating a pin map file would be a good starting point. Then sort out the clock tree configuration. I usually create a processor specific project to verify the USB connection and then copy the clock tree setup from that to the grblHAL driver - I have done so many times for the STM32F4xx driver.

Did you manage to create a map file?
