Duet 3 MB6HC V1.01 I2C Connection

[NeueKlasse]

Is it possible to use the i2c protocol to communicate with the MB6HC Board?
(M260/261)
Which Connector to use? IO2 is documented with
„I2c possible with added Resistors“
But no further information

I want to connect a EEPROM to it.

@neueklasse in theory the MB6HC could support I2C on IO2 if the input protection resistor was bypassed. On the next MB6HC revision we will probably add a jumper to make it easy to bypass this resistor.

However, the MB6HC build of the firmware doesn't currently support I2C.

@dc42 Is it possible to get a Schematic and Circuit drawings from the Board itself?

@neueklasse the Schematic is here:

I will move this to the firmware wishlist.

@t3p3tony thanks!
