The pull-up resistors may be placed on either half. If you wish to use the halves independently, it is also possible to use 4 resistors and have the pull-ups in both halves. +Note that the total resistance for the connected system should be within spec at 2.2k-10kOhm, with an 'ideal' at 4.7kOhm, regardless of the placement and number. <img alt="sk-i2c-connection-mono" src="https://user-images.githubusercontent.com/2170248/92297182-92b98580-ef77-11ea-9d7d-d6033914af43.JPG" width="50%"/> |
