Q: How many addresses can the IIC allocate? How many TFmini can be connected to a TFmini IIC bus?

A: According to the manual, IIC address range is 0x10~0x78, so it can support up to 105 independent addresses theoretically. 
Regarding the number of connectables, the connection of 5 or 6 have been test. In theory, dozens of them can be connected.
Note that when there is excessive load on the IIC bus, high frequency communication may be affected because the capacitance between the buses cannot be fully charged.
