@nic_o_martin This is the exact model I got: amazon.de/dp/B072XTKKVR/ref=pe_27091401_487024491_TE_item?th=1. Have to say it sometimes is hard to connect to and requires a few attempts. I have a vague feeling it has to do with power. The USB port on my Mac in battery seems to not like it. Better when Mac and Arduino are plugged in.
