Socket Boards
Socket boards are package or sensor-specific boards designed to simplify sensor evaluation and improve the user experience. They provide a convenient, ready-to-use solution that requires no external wiring for standard evaluation. Each board includes a burn-in test socket, application-level components, test points, and a header connector for easy access to sensor signals. The header connection can also be used to interface with sensors mounted on a demo board or in a customer application through an external wire harness. Note: Socket boards are supplied without the sensor installed.
