Note: As MKS Robin Nano V2.0 doesn't has an independent serial port, so if using with the MKS H43, V2.0 cannot work with Wifi module, but V3.0 can make it.
The hardware design is openned source on : https://github.com/makerbase-mks/MKS-Robin-Nano-V3.X/tree/main/hardware
The factory firmware of Nano V3 is based on Marlin 2.x, actually, we directly use the same respository of Nano V1.2/2.0:https://github.com/makerbase-mks/Mks-Robin-Nano-Marlin2.0-Firmware. Just modify the type of motherboard to compile the related firmware.
Now Nano V3 also supports RepRapFirmware (RRF). For details, please refer to:https://github.com/makerbase-mks/RepRapFirmware-for-MKS-Boards
Nano V3 has supported klipper firmware. For details, please refer to:https://github.com/makerbase-mks/Klipper-for-MKS-Boards
