agree! @holger80 would be definitely a great choice. His library works pretty nice and I was able to have my first bot running within a quite short time.
I am new to python but have "some" (about 40 years) of experience in hardware development, different type of microcontrollers coded in C or even Assembler....
So maybe if there is something like hardware-wallet to be developed one day or hardware safe for keys... Something like this :-) I could do from scratch with prototype and PCB-Layout.
