I am planning a circuit that requires two-way communication between one esp32 and 3 others. I want to use a master/slave architecture as shown here: Planned ArchitectureThey need to be able to communicated via hardware, not wirelessly!
Is this possible using the following circuit? 1 (in this circuit, the CLK pins are serial clock pins and the SD pins are serial data pins, i plan to use i2c (which may also need the arduinos to have a common ground...))

Any solutions/ideas are appreciated
