Circuit schematic labelled N91D Apollo SI, with a 1027A revision or date code. In design-stage naming, SI usually means system integration, an early build, so the document may differ from the production board. No brand or board number is stated. The 1.51 MB PDF is suitable for tracing power rails and signal paths and for locating parts while diagnosing a fault. Before using it, check the board number and revision printed on the PCB against the schematic title pages, because early builds are often revised.
