Voltages made by the WPC power driver board
The power driver board is both the power supply and the driver board. It makes +5 V for logic, +12 V for the switch circuit, +12 V for motors and relays, +18 V for the lamp matrix, +50 V for coils and +20 V for flashers, and it drives every coil and lamp.
