An on-board Microchip 24AA32AT device provides an added storage device for factory settings:
* the first 32 bytes of the device '''are RESERVED''': this region stores the bytes for the [[ConfigID_and_UniqueID#I2C_Eeprom|ConfigID]] on BORA SOMs configured for booting from NAND device (without NOR SPI on board)
* three address pins for configuring the I2C adddress A0, A1, A2 internally configured as A[0..2]='000'
* the EEPROM_WP is connected to J2.78 pin and '''should not be externally connected'''
