Hi everyone
a device ID that is not listed but succesfully accepts MF firmware via avrdude is still not detected in modules. (also accepts sketches from IDE)
VID_0843&PID_5740
this one is now very common on AliExpess.
Can this be added in future releases? I am not familiar with compiling source code etc.

Cheers,
Pat

It just needs to be added to the arduino_nano.board.json file. You can try yourself, the file is in the mobiflight folder in the boards folder.

#

Add it in there, you'll see the pattern from the other ones, and if it works open an issue in GitHub with the information

What is different about this new Nano besides de vid/pid?

#

Please provide a link

#

nothing different. just vendor id. counterfeit atmega chips i think

#

Feel free to open a github issue to add this, I believe there's a specific issue type for the request

@autumn raft do you have a picture of this Nano from the top side where the marking of the USB seriell I can be seen?
Or a link to this board?

#

there is no link to this board as the pictures on AliExpress vary from the product eventually received. Heres a picture

#

#

chips are blank and maybe vaguely only the top one reads Atmel. but most likely fake.

#

The chip on the bottom seems more interesting to me

#

The atmel chip has nothing to do with what the board is recognized as

#

Yeah, that would be great.

#

To see the chip on the bottom.

google seems to think it is not CH340G but FT232R

For what I have found out it's not a CH340 chip and not a FTDI chip. So interesting that it works with the VID/PID combination in the json file.
Furthermore this board uses a 328PB chip and not a 328P one. The 328PB has two additional I/Os, PE0 and PE1 which are routed to two additional pins near the ISP connector.

oh, clever to repurpose the two mounting holes for that!
