Electronics for operating turnouts and signals

Mini-Driver module

This is the basic unit, called a mini-driver. It has the ability to directly control 8 outputs and can also be expanded to 32 outputs.
Only the first 8 outputs, which are directly controlled by the microcontroller, can operate time-multiplexed lamps.
There are two versions, the one on the left has only 8 outputs and room for extra circuitry (such as a Capacitive Discharge Unit and serial "FRAM" memory), the unit on the right has 16 outputs.
