Purpose |
</h1> |
<p> |
Basic reason for existence of MLAB is the need for opened robust and |
somehow universal kit (as a box of universal bricks) for both electronic |
hobbyists and professionals. MLAB is focused on general electronics and |
microcontroller technology. It can be used for tuition as well. |
</p> |
<h1 class="FirstWord Small"> |
Features |
</h1> |
<p> |
For serious work it is necessary to use system rigid enough to get good |
reliability and mechanical stability. It is reached by base board |
usually made from single sided PCB material. The board is not only |
mechanical support but it is a good ground as well. |
</p> |
<p> |
The base is furnished by holes for fastening of individual MLAB modules. |
The holes are places on a grid every 10.16mm (0.4inch). Dimension of a |
module can be any integer number of grid and screws are usually places |
to all four corners. |
</p> |

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

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