Osamu2-dis-kb-hpc Mv-mb-v1 Schematic May 2026

The "osamu2" SoC likely reads boot configuration from pull-up/pull-down resistors on power-up. The schematic must clearly label these:

For Arm-based osamu2:

&i2c3 
    keyboard@5a 
        compatible = "osamu2,kb-matrix";
        row-gpios = <&gpio1 10 GPIO_ACTIVE_HIGH>;
        col-gpios = <&gpio1 11 GPIO_ACTIVE_HIGH>;
    ;
;

Before examining the schematic, we must decode the naming convention. This follows a military/aerospace standard for module versioning.

Revision: v1
Date: [Insert Date]
Designer: [Your Name/Team]
Board Type: Motherboard (MB) with integrated display (DIS) and keyboard (KB) interface, HPC module carrier

The schematic reveals a sophisticated power tree. Input is a wide-range DC (18-36V, e.g., MIL-STD-1275). This feeds:
