Describe GNSS1 and GNSS2 as RGB LEDs on outputs 0 through 5 and SMA1 through SMA4 on outputs 6 through 17. The board uses a 4.7 kohm RISET resistor, sequential red, green, and blue output wiring, and an 8100 uA per-output limit. Select this profile only for the exact fixed-width EEPROM ID "TIMECARD-V9". Earlier revisions expose the same I2C devices with different LED routing, so probing cannot distinguish them safely. Leave erased, malformed, and unknown board IDs unconfigured.
