In my thesis I would like to introduce a recently emerging phenomenon, while

showing a possible solution to it through the engineering and assembling process of a

certain modular circuit.

With the spreading of the popular easy-to-use and highly personalisable (and also

quite inexpensive) embedded boards (such as Arduino or Raspberry Pi), it’s got clearly

visible that most of these boards do not have sufficient electrical and mechanical

protection features which makes them inapt to perform in industrial environment.

The device designed by me and discussed in this thesis tries to prove that

cheapness, versatility, utility and enhanced electrical protection can be achieved at the

same time, while keeping it code compatible with the Arduino system.

For improved utility, the device also has a powerful H-bridge DC-motor driver on

board containing only N-channel MOSFETS and a full bridge driver, making it easy to

design new H-bridge circuitry with different power requirements and without the

disadvantages of P-channel MOSFETs.

The housing of the board -which is responsible for the mechanical protection- is

not discussed in this thesis.
