2.3.15 Button
The placement of the buttons SW1 -
SW4 is protected against polarity
reversal. You have to place it onto the
board with soft pressure till it snaps in.
(see the picture of the finished main
circuit board on page 15).
2.3.16 Switch
The toggle switch S1 may be soldered
onto the board in both possible
orientations, the functionality stays the
same.
2.3.17 Electrolytic capacitors
During placement of the 470µF
electrolytic capacitor (C17), the
100µF electrolytic capacitor (C3) and
the two 4,7µF electrolytic capacitors (C5 and C11) onto
the board you have to pay attention to the polarity:
The positive connections are marked with “+” sign on
the board. The positive pin of the electrolytic capacitor is
the long leg and the negative one is the short leg. The
negative connections are implemented by thermal vias.
You can find a “-” symbol on the housing of the capacitor.
2.3.18 Potentiometer
Placing the potentiometer R29 you have
to pay attention to the polarity: there is
only one possible orientation. The
potentiometer is to adjust the sensitivity of
the odometry sensors.
