Re-consider the use of eMMC Modules #65

Closed Kreyren closed 2 months ago

Kreyren commented 1 year ago

Context

a while ago i proposed this to tsvetan to use the eMMC modules commonly used by hobby-oriented companies to make their emmc's swappable without the need of soldering such as:

afaiu he didn't like the idea bcs OLIMEX's consumers are mostly from the industrial sector where such use is likely to cause issues with data transfer due to e.g. vibration

Proposal

Consider adjusting the pinning on the teres to make it possible for the user to unsolder the eMMC and add a pre-designed daughter board on it's place that would enable the swappable emmc without soldering on demand that way.

Rationale

It would make the laptop significantly more hackable and the daughter boards could be easily adjusted to other connector solutions e.g.

And in practice the hypothesis is that it would basically mean just adding power pins hidden under solder mask around the chip while allowing an easier hacking for the eMMC as that way i don't have to handle jumper wiring from appropriate power source to address energy demands of alternative chip in https://www.olimex.com/forum/index.php?topic=9095.0

Judging by https://www.olimex.com/Products/SOM/NXP-iMX8/iMX8MP-SOM-EVB-IND/ it appears implemented.
