Hi,

I am trying to understand the transponder ordering & flashing process via JLCPCB. I tried to place the order via the web user interfacel.
- Delivery Format option:
If I choose single PCB I get a error message about duplicates later after uploading bom and pos files. I could instruct to ignore it, but not sure whether that is right.
If I choose panel by customer (which also sounds about right), I am asked to enter dimensions. When I enter 2 columns 4 rows, I end up with a total cost, that is above 600 USD. Doesn't sound right either.

- What are you recommending as surface finish option?

- Flashing the firmware:
I think I can take the easy way and skip the build process and directy jump to flashing the Main.hex file from the release package using the STM32CubeProg tool linked earlier in the thread (although avrdude is mentioned in github)
However, what hardware do I need to connect to the transponder? Do I need a full Atmel ICE kit? Google returns a huge range of devices.

Thanks a lot!
