CONF
Main Logic Board (PCA)
The Roomba s9 frequently experiences internal communication faults (Error 31) where the main processor can no longer poll data from the sensor suite, including the camera and 3D depth sensor. This failure is typically rooted in the degradation of the power management ICs or the I2C bus on the main logic board. Replacing the PCA restores the communication path between the CPU and the robot's navigational hardware, clearing the 'Error' state.
