Describe GNSS1 and GNSS2 as RGB LEDs on outputs 0 through 5 and SMA1 through SMA4 on outputs 6 through 17. Select this profile only for the exact EEPROM ID "TIMECARD-V9". Earlier Time Card revisions expose the same I2C device population with different LED routing, so probing cannot distinguish them safely. Leave erased, malformed, and unknown board IDs unconfigured.
