I²C address map

Two devices on one address is the classic I²C bring-up failure. Here is every address these parts claim, and where they collide.

Cannot share a bus, ever

Both parts are fixed to the same single address with no strap pin. No wiring change helps: you need an I²C multiplexer such as a TCA9548A, or a second bus.

Collide by default, fixable by re-strapping

These overlap on their default addresses, but at least one has an alternate. Tie the address pin the other way and they coexist fine.

Full map, 0x08 – 0x77

Addresses below 0x08 and above 0x77 are reserved by the I²C specification and are not usable by devices.
