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 |
| 54 |

61 |
microcontroller technology. It can be used for tuition as well. |

<p> |

|
67 |
For serious work it is necessary to use system rigid enough to get good |
| - |
|
68 |
reliability and mechanical stability. It is reached by base board |
| - |
|
69 |
usually made from single sided PCB material. The board is not only |
| - |
|
70 |
mechanical support but it is a good ground as well. |
| - |
|
71 |
</p> |
| - |
|
72 |
<p> |
| - |
|
73 |
The base is furnished by holes for fastening of individual MLAB modules. |
| - |
|
74 |
The holes are places on a grid every 10.16mm (0.4inch). Dimension of a |
| - |
|
75 |
module can be any integer number of grid and screws are usually places |
| - |
|
76 |
to all four corners. |

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

For power supplies it is used the same jumper connectors. Usually this |
| - |
|
94 |
way: |

|
96 |
<ul> |
| - |

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