'''nx-abca2''' ('''Icosa''' in '''Erista''', '''Iowa''' in '''Mariko''') hardware types are variations of the retail and EDEV form factors.
'''nx-abca2''' ('''Icosa''' in '''Erista''', '''Iowa''' in '''Mariko''') hardware types are variations of the retail, EDEV and SDEV form factors.
'''nx-abcb''' ('''Copper''') is the SDEV unit. Among other differences, this has extra hardware to support HDMI output.
'''nx-abcb''' ('''Copper''' in '''Erista''', '''Calcio''' in '''Mariko''') is a prototype unit. Among other differences, this has extra hardware to support HDMI output.
[8.0.0+] '''nx-abcc''' ('''Hoag''') was added for '''Mariko'''.
[8.0.0+] '''nx-abcc''' ('''Hoag''') was added for the Lite retail and HDEV form factors.
'''Erista''' memory is LPDDR4, while '''Mariko''' memory is LPDDR4X.
'''Erista''' memory is LPDDR4, while '''Mariko''' memory is LPDDR4X.
