Hey there, @Rob308771, and welcome to the forum. Glad to have you here.
Technically, there’s a couple of different answers to this question.
To give you the easy and realistic answer: 5 or 6.
Slightly more complicated answer: 8. Using the binary switches, you can assign each board to one of the addresses 0x08->0x17. You might need to cut the I2C PullUp Resistors for that to work, however, as outlined below:
Hi Jane, Thankyou for the prompt reply. Most helpful Thankyou

No worries, Rob. Have a lovely weekend.
This is an interesting case for the CE07910. Using them with a Jetson Orin Nano devkit they seem to take out the i2c bus. I have attached about 7 other types of piicodev modules that all work fine. The LED RGB modules (tried 4 different ones) always kills the i2c bus. I have tried cutting the pull up connections, still kills the bus. I can only think maybe the 100KHz speed is the issue but I need it for imus.
