STEVAL-PROTEUS, 34 pin adapter

[Peter15]

Hi,
the STEVAL-PROTEUS has a 34-pin expansion connector.

in UM3000 User manual is written:
"The pinout of the 34-pin connector is compliant with the STMOD+ by using a dedicated adapter (not included in
the kit)."

Where can I buy such a dedicated adapter?
Or any advice on how to make a cable to use the USART1?
Thanks, Peter

How could the STEVAL-PROTEUS1 be used with a STEVAL-STMODLTE?
