We can support the open-source community to develop this as a solution together with minimum order requirements and R&D in this area. To use the ATmega328P microcontroller, or ARM version would take rewriting the Firmware/Software and redesigning the current circuit’s architecture.

If you don’t absolutely need Arduino, you have access to the firmware via a USB programmable in C if you aren’t trying to port over something.
