=== Introducción ===

ROCK Pi 4 no incluye almacenamiento en la propia placa, usa un módulo eMMC en su lugar. Los beneficios de un módulo eMMC para el usuario son: que este puede escoger la cantidad de almacenamiento deseada, puede cambiar de Sistema Operativo y la placa es más fácil de producir.

=== Módulo eMMC ===

[[File:Emmc_module_black_top.png | 100px]] [[File:Emmc_module_black_bottom.png |100px]]

'''Note''': the green PCB and black PCB are the same, just color difference.

The eMMC socket on ROCK Pi 4 uses two B2B connector to mount the eMMC module, the connector model is [http://www.lsmtron.com/pdf/Connector&Antenna_catalog.PDF GB042 Series], one connector(34pin) for eMMC signal, the other(30pin) is for mount purpose only. This pinout of the 34pin is compatible with Odroid(Thanks Odroid for sharing their pinout).

* on board: GB042-34S-H10 (socket-34pin) + GB042-30S-H10 (socket-30pin)
* on eMMC module: GB042-34P-H10 (Plug-34pin) + GB042-30P-H10 (Plug-30pin)

The eMMC chip we use is branded as Foresee, by Longsys, a Shenzhen embedded storage company, who acquires Lexar Brand in 2017.
