I2C Expander

[XORadmin]

I just mean the older tiptop modules used to use similar 3.5mm jacks with the black plastic receptacle. I did not appreciate them. Is there a reason for the switch on the i2c expander?

Oh I see. Yes the reason is that this is the only way to keep galvanic separated for the Midi port when using an aluminium Frontpanel. Thats why the 2HP Midi is only available with a PCB Frontpanel.

For the I2C port it doesn’t matter but for the Midi Port it is the only way to keep the specs.
