These are pre-built Matter images that are ready to flash onto ESP32 boards. They are built from the repo https://github.com/project-chip/connectedhomeip.

• matter-program.bin is the merged firmware file from the other files within respective folder
• all-clusters example has all features like tempearture, thermostat, heater, light, color, brightness, on/off, lock, window, etc.
• lock-app is a door lock example
