Red mach3 USB board

[gschielack]

Hi, I just finished building a plasma/router table using using one of these red mach3 USB board from AliExpress. It is up and running on mach3, but I have an extra board and I'd like to try grblhal, but it doesn't have the stm321xx chip. It has an AT32F403ARCT7. I'm assuming it's not safe to flash the web builder stm32f1xx file. Is that correct? And if not, will there be any support for it? Thanks

Correct, it is a likely STM32F403 clone - IIRC with its own SDK.

And if not, will there be any support for it?

Only if someone can get it to work, I am not going to spend time on it. I could be as "simple" as adding F403 support to the STM32F4xx driver, or if a different SDK is required writing a new driver using that.
