That's it, silly me, let's give it a try: it produces a nice interface filled with probably lawful chinese options. There is another file called -ú+ÚÁ¸-È.EXE in the INSTALL directory. Marlin serial number date of manufacture. Let's try something else, maybe they are not bad people. I like this 'preinstalled' and 'in advance' part though. It copies some ch341***.*** files in ***/system32/drivers and displays proudly 'The drive is successfully Pre-installed in advance!'. and they would provide instructions (they did)īut, we are geeks: one would execute ch341ser.exe and expect the driver setup will do the job. no issue should be simple IF the manufacturer of the chips would provide a driver, they didĢ. The PROBLEM, they use CH341 chips not the Arduino standard FDDI ones and you need to install a driver:ġ. There are very cheap Arduino nano chinese clones there.
