`#define EXTERNAL_EEPROM_PAGE_SIZE` | `32` | Page size of the EEPROM in bytes, as specified in the datasheet
`#define EXTERNAL_EEPROM_ADDRESS_SIZE` | `2` | The number of bytes to transmit for the memory location within the EEPROM
Default values and extended descriptions can be found in `drivers/eeprom/eeprom_spi.h`.
Alternatively, there are pre-defined hardware configurations for available chips/modules:
