The MLC mega is a magnificent version of the MattzoLayoutController that can be used to control 16 servos, 8 light signals and 16 sensors at the same time.
It can also be configured to work as a controller for level crossings, bascule bridges and turn tables.

The controller has one built-in PCA9685 servo port extender and two built-in MCP23017 I/O port extenders. The case has a lateral dimension of 10×10 studs (8 x 8 cm) and is 5 bricks high (4,8 cm).

The case uses especially designed PCBs and comes with a case that can be easily created with a 3D printer.

We are presently preparing an improved version of the MLC mega that will likely be a big smaller and easier to build.
Other MattzoLayoutControllers
The MLC mega is not alone. It has a small brother, called MLC mini, which is a bit smaller and easier to build.
