54 Purpose
55 </h1>
56 <p>
57 Basic reason for existence of MLAB is the need for opened robust and
58 somehow universal kit (as a box of universal bricks) for both electronic
59 hobbyists and professionals. MLAB is focused on general electronics and
60 microcontroller technology. It can be used for tuition as well.

63 Features
64 </h1>
65 <p>
66 For serious work it is necessary to use system rigid enough to get good
67 reliability and mechanical stability. It is reached by base board
68 usually made from single sided PCB material. The board is not only
69 mechanical support but it is a good ground as well.
70 </p>
71 <p>
72 The base is furnished by holes for fastening of individual MLAB modules.
73 The holes are places on a grid every 10.16mm (0.4inch). Dimension of a
74 module can be any integer number of grid and screws are usually places
75 to all four corners.

79 alt="Assembling of modules on the base"></a>
80 </p>
81 <p>
82 Electrical connections are made by stranded wires with female connectors
83 on both sides. On modules there are prepared jumper connectors in common
84 raster 2.54mm (that is 1/10 inch). Wires can be easily obtained from old
85 printer cable. There are a lot of wires of different colors, almost free.

90 </p>
91 <p>
92 For power supplies it is used the same jumper connectors. Usually this
93 way:
94 </p>
95 <ul>
96 <li>
97 For +5V 3-pin jumpers are used. Both side pins are grounds and middle
98 pin is power. This type of connector is used for stabilized +5V or for
99 small voltage from batteries.
100 </li>
101 <li>
102 For power above +5V (typically +12V or +16V for programmer or for
103 power electronics it is used 4-pin jumper connectors. Both side pins
104 are ground and two middle pins are power. It is supposed that
105 experimenter knows that he deals with “hi voltage” that can be
106 dangerous for some devices.
