Leo looked down at the D10-240p1a. In the dim light, the jagged-line symbol seemed to pulse, just slightly, like an echo trapped in the ink.

The D10-240P1A is a designed for SFF PCs. It was used in:

In electronics, parts like D10, D240 might refer to diodes. The "p1a" at the end could indicate the part number or some specification, maybe power rating (like 1A) or polarity. The schematic would then represent a circuit using these components. But since I can't confirm, I need to make this part flexible in the paper.
