For those performing micro-soldering or board-level repairs, the following resources are commonly used by technicians to compensate for the lack of official schematics:

A separate board handles the USB-C port, LAN port, and card reader connections, connected to the mainboard via a ribbon cable.

The OLED model upgrades internal storage to 64GB. Crucially for repair technicians, the eMMC storage chip is no longer on a modular, detachable daughterboard like the V1/V2 models. It is permanently soldered directly onto the main PCB (BGA package). The schematic maps out the standard 8-bit MMC interface lines directly routing to the Tegra SoC.
