AW93x05 electrode breakout

A 24 × 24 mm two-layer prototype for AW93105DNR, with AW93205DNR and AW93305DNR as alternative fitted devices. Five sensor channels, I²C, interrupt and 3.3 V power are exposed on headers. The alternatives need device-specific firmware.

This is an independent electrode experiment. It does not substitute for the AW96105 fitted to the current ear. Supplier acceptance and bench qualification remain open.

See the connections and population guide.

Schematics and assembly

• Schematic PDF — includes hierarchical sheets.
• Interactive BOM and board inspector.
• Component BOM (CSV).
• Exact saved PCB snapshot.

These are development documentation exports. The BOM is not a supplier upload file. Manufacturing packages and supplier acceptance are tracked by the board's build recipe.
