Circuit Mapping Notes
Request
Reverse-engineer the circuit from IMG_20261012_190702.jpg (component side) and IMG_20261012_190723.jpg (copper side).
Observations from the supplied photos
- An irregular single-sided board with several exposed switch-contact patterns on the copper side.
- The component side has two visible axial resistors labelled R1 and R2, two upright capacitor-like components, and a small black component whose marking is not legible at this resolution.
- Green and yellow wires lead to a round piezo-like sound element visible in the copper-side photo.
- Visible legends include SP+, B+, GND, SELECT SOUND, ON, OFF, UP, RIGHT, DOWN, LEFT, K.LOW and K.HGH. These labels are observations, not verified net assignments.
- Multiple solder joints and traces are visible, but the supplied resolution, wires covering the component side, and unreadable component markings prevent a reliable complete pin-to-pin schematic from being established from these images alone.
State
No components or nets have been created. No connectivity has been verified and no schematic has been reconstructed. The project was empty at the start of this request.
Resume work
- Align the two images, accounting for the mirrored view of the copper side.
- Inventory components and read markings from higher-resolution close-ups, especially the black component and the upright components.
- Trace copper connections and distinguish verified paths from ambiguous ones; use unpowered continuity measurements for uncertain connections.
- Reconstruct the schematic and label unknown values explicitly, rather than guessing.
Execution stopped because the user's ACUs ran out before circuit tracing or schematic creation could begin.
