 * More preset could be add upon time or on request.
 * Preset MatrixPreset values currently available:
 *      - SBK_BarMeter_SK28 : Alias for **SBK BarMeter SK28** PCB using the BL28_3005SK preset.
 *      - SBK_BarMeter_SA28 : Alias for **SBK BarMeter SA28** PCB using the BL28_3005SA preset.
 *      - BL28_3005SK       : Native mapping for BL28-3005SK bar meter (7×4 layout, common cathode).
 *      - BL28_3005SA       : Native mapping for BL28-3005SA bar meter (4×7 layout, common anode).
