A close view of a green circuit board shows capacitors, connectors and other components.

The board is held at an angle above a dark workspace, with loose screws resting below and a laptop keyboard at the edge of the frame. Printed values are visible on several parts; this sheet does not rely on them.

A large square chip sits towards the top right, out of focus. It is listed, not identified.

Callouts

  1. A blue multi-pin connector runs along the left edge.
  2. Cylindrical capacitors stand in a loose cluster; their printed values are not relied on here.
  3. A small red switch sits beside a black socket at the corner.
  4. Brown residue surrounds the corner mounting hole.

Revisions

  1. Rev A · · First look

    Listed the edge connector and the capacitor cluster.

  2. Rev B · · Corner detail

    Added the residue around the mounting hole. Its cause is not stated; the photograph does not show it.
