Hi!
I am currently trying to build a GPS sensor that communicates over I2C with the nucleo Board, but i'm not sure about the documentation.
So I started a new CubeMX Project based on the NUCLEO WL55JC1 and, according to the software (as shown in pic 1), the I2C1 Pins are PA10 (SDA) and PB8 (SCL).
However, according to the manual the pins should be PA11 and PA12, wich would be pin 9 and 10 on the CN5 connector (shown in pic 2).
So.. wich one's correct?
Thanks in advance!

Hello @GHube.1 ,
in UM2592 rev1, Table 17: CN5 (Pin number 9 and 10) functions should be I2C2_SDA (PA11) and I2C2_SCL (PA12).
(not I2C1_SDA and I2C1_SCL as indicated).
I raised the typos internally for fix in the coming release of User manual UM2592.
Thanks for your contribution.
