'''nx-abca2''' ('''Icosa~~''' or '''Hoag~~''' in '''Erista''', '''Iowa~~''' or '''Hoag~~''' 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 and EDEV form factors.

'''nx-abcb''' ('''Copper''') is the SDEV unit. Among other differences, this has extra hardware to support HDMI output.

[8.0.0+] '''nx-abcc''' was added for '''Mariko'''.

[8.0.0+] '''nx-abcc''' ('''Hoag''') was added for '''Mariko'''.

'''Erista''' memory is LPDDR4, while '''Mariko''' memory is LPDDR4X.

[1.0.0+] This item is obtained by checking bits 8 and 2 from [[Fuse_registers#FUSE_RESERVED_ODM4|FUSE_RESERVED_ODM4]]. It can be 0 (Icosa), 1 (Copper), 2 ~~(Hoag~~) or 3 (Invalid).

[1.0.0+] This item is obtained by checking bits 8 and 2 from [[Fuse_registers#FUSE_RESERVED_ODM4|FUSE_RESERVED_ODM4]]. It can be:

* 0 ('''Icosa'''; Erista retail and EDEV), if development flag (bit 8) is '''Retail''' and production flag (bit 2) is '''Production'''.

* 1 ('''Copper'''; Erista SDEV), if development flag (bit 8) is '''Development''' and production flag (bit 2) is '''Prototype'''.

* 3 (Invalid).

~~[4.0.0+] This item~~ is ~~obtained by checking bits 8, 2~~ and ~~16-19 from [[Fuse_registers#FUSE_RESERVED_ODM4|FUSE_RESERVED_ODM4]]. It can be 0 (Icosa), 1 (Copper), 2 (Hoag), 3 (Iowa) or 4 (Invalid)~~.

Value 2 is reserved and considered invalid.

[7.0.0+] This item ~~no longer depends on fuses~~ and can ~~only~~ be 0 (Icosa) ~~or 0xF~~ (Invalid) ~~in retail units~~.

[4.0.0+] This item is obtained by checking bits 8, 2 and 16-19 from [[Fuse_registers#FUSE_RESERVED_ODM4|FUSE_RESERVED_ODM4]]. It can be:

* 0 ('''Icosa'''; Erista retail and EDEV), if development flag (bit 8) is '''Retail''' and production flag (bit 2) is '''Production'''.

* 1 ('''Copper'''; Erista SDEV), if development flag (bit 8) is '''Development''' and production flag (bit 2) is '''Prototype'''.

* 3 ('''Iowa'''; Mariko retail and EDEV), if new hardware type (bits 16-19) is '''Iowa'''.

* 4 (Invalid).

[8.0.0+] This item can be 0 (Icosa), 1 (Copper), 2 (Hoag), 3 (Iowa), 4 (Calcio) or 5 (Invalid). It still ~~can~~ only be 0 (Icosa) or 0xF (Invalid) in retail units.

Value 2 is reserved and considered invalid.

[7.0.0+] This item can be obtained by checking bits 8, 2 and 16-19 from [[Fuse_registers#FUSE_RESERVED_ODM4|FUSE_RESERVED_ODM4]], but is now only 0 (Icosa) or 0xF (Invalid) in retail units.
