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

64 Features
65 </h1>
66 <p>
1909 kaklik 67 In opposite to another more known projects such as Arduino the MLAB is not a development platform
68 focused to only one architecture of microprocessors but uses many types of chips from much
69 manufactures. In addition the MLAB provide much better design reliability which is achieved by using
70 the base board usually made from aluminium or single sided PCB material. The board is not only
71 mechanical support but it is a good ground conductor as well.

73 <p>
74 The base is furnished by holes for fastening of individual MLAB modules.
75 The holes are places on a grid every 10.16mm (0.4inch). Dimension of a
76 module can be any integer number of grid and screws are usually places
77 to all four corners.

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

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