The MEM24CXX is a STM32World board containing 1-4 I²C 24Cxx_I²C_EEPROMs.
I²C Address(es)
A scan of the I²C bus with the board attached and 4 24Cxx_I²C_EEPROMs mounted, show the following:
Scanning I2C bus: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50 51 52 53 54 55 56 57 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
Each 24Cxx_I²C_EEPROM will occupy two addresses with a 64k page on each (so 128kB for each EEPROM.
