Time Card V9 boards use the same mux infrastructure with a BME280, a BNO055, and an IS32FL3207 at a different address.
Describe six RGB groups. The first two expose the GNSS1 and GNSS2 status LEDs on outputs 0 through 5; the remaining four expose the SMA indicator LEDs on outputs 6 through 17. Select the profile only when the fixed-width board ID exactly matches TIMECARD-V9 with zero or erased-byte padding. Older revisions share the detectable I2C devices but not the V9 LED wiring.
