just a heads up -
on [https://learn.bela.io/using-bela/technical-explainers/pins-used-by-bela/]
it says
i2c2_scl | P9_19
i2c2_sda | P9_20
but on [https://learn.bela.io/pin-diagram/] it puts these on P9_24 and P9_26, respectively.
not that i'm using them, but it might cause some frustration. unless both are correct 
They are both right:
the cape uses i2c2_scl | P9_19 and i2c2_sda | P9_20, which is bus I2C2, for the audio codec. However, the pin diagram recommends that you use I2C1 for connecting external devices, and that's on P9.24 and P9.26.
EDIT: I2C2 remains largely free (except address 0x18, used by the codec) if you need to use it for something else
aha! thanks for clarifying
