The MLC mega<\/strong> is a magnificent version of the MattzoLayoutController that can be used to control 16 servos<\/strong>, 8 light signals<\/strong> and 16 sensors<\/strong> at the same time.<\/p>\n\n\n\n

It can also be configured to work as a controller for level crossings, bascule bridges and turn tables.<\/p>\n\n\n\n

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).<\/p>\n\n\n\n

The case uses especially designed PCBs and comes with a case that can be easily created with a 3D printer.<\/p>\n\n\n\n

Then solder the power plug on the PCB<\/figcaption><\/figure>\n\n\n\n
\"\"
You need some more solder because of the relatively large gap<\/figcaption><\/figure>\n\n\n\n
\"\"
Install two 10k resistors<\/figcaption><\/figure>\n\n\n\n
\"\"
Add the AMS1117<\/figcaption><\/figure>\n\n\n\n
\"\"
Create a galvanic connection between IN+ and OUT+<\/figcaption><\/figure>\n\n\n\n
\"\"
Install the connector next to the microcontroller. This will provide the connection to the upper board later<\/figcaption><\/figure>\n\n\n\n
\"\"
Solder 32 120 Ohm resistors onto the upper PCB<\/figcaption><\/figure>\n\n\n\n
\"\"
Add the two MCP23017s and the connectors for the sensors and signals<\/figcaption><\/figure>\n\n\n\n
\"\"
Solder two capacitators next to the MCP23017<\/figcaption><\/figure>\n\n\n\n
\"\"
From the PCA9685, you need to remove the two elements marked with the red box<\/figcaption><\/figure>\n\n\n\n
\"\"
Solder a new capacitator on the other side of the PCA9685. Watch the correct orientation of the component. Mount the holders<\/figcaption><\/figure>\n\n\n\n
\"\"
Solder a cable onto the PCA9685 and lead it as shown to the backside of the port extender<\/figcaption><\/figure>\n\n\n\n
\"\"
prepare the cable on the other end<\/figcaption><\/figure>\n\n\n\n
\"\"
Crimp some connectors on it and solder them onto the upper PCB<\/figcaption><\/figure>\n\n\n\n
\"\"
Mount the lower PCB and the PCA9685 into the case<\/figcaption><\/figure>\n\n\n\n
\"\"
Place a second connector (red box) onto the first one<\/figcaption><\/figure>\n\n\n\n
\"\"
Mount the upper PCB, place single connector pins into the correct holes to establlish the connection to the lower board<\/figcaption><\/figure>\n<\/figure>\n\n\n\n

We are presently preparing an improved version of the MLC mega that will likely be a big smaller and easier to build.<\/p>\n\n\n\n

Other MattzoLayoutControllers<\/h1>\n\n\n\n

The MLC mega is not alone. It has a small brother, called <\/a>MLC mini<\/a>, which is a bit smaller and easier to build.<\/p>\n\n\n\n
