Which component do you mean? Send its schematic designator (for example, **U1**, **D2**, or **J3**), exact part number, or a screenshot showing it. I couldn’t inspect or change the project in this session because execution stopped when your ACUs ran out.

**D1, D3, and D4 are diode designators**, but I can’t verify which exact diode or part number is assigned to each from the available project summary. The board uses at least these diode types: - **SS34** — 3 A, 40 V Schottky rectifier, commonly used for reverse-polarity protection and switching-converter current paths. - **0603 LED** — an indicator light; its exact color and manufacturer part number may not be specified. To identify each one precisely, open D1, D3, and D4 and check their **Value/MPN** fields, or send a screenshot of that schematic area. I couldn’t inspect them directly because execution stopped when your ACUs ran out.
