2.4 Visual inspection of the circuit board
Before the board is attached for the first time to a power supply, all electrical
components must be checked for the correct assembly. Therefore you have to
check all values.
Afterwards you have to pay attention to the polarity and the correct installation
respectively.
Finally check the board for short circuits and make sure that neither on the
top side nor on the bottom side of the board remains any solder or wire.
!! Important !!
The robot must never be switched on without inserted IC2 (74HC139),
otherwise the transistors for the motor-control will be destroyed!
Information:
Particularly the via's (vertical interconnect access), the picture shows four of
them for example, should not be connected together with solder spots!
