    Hello Toshi,

    This configuration is not possible as any clock stretching on the 5 V side by one of the slaves will not be seen by the other two and will cause issues.

    This will work if you switch make the A side 3.3 V and the B-side 5 V (keep the 4th TCA9517 on Board-C the same).

    Regards,

    Andrew
