2.5.6 Insertion of the ICs
!! Important !!
The NIBObee must never be switched on without inserted IC3
(74HC139), otherwise the transistors for the motor-control will be
destroyed!
The four ICs must be put with careful pressure into the sockets. The notch
on the IC has to point in the same direction as the marks on the board
and the socket!
IC1: ATmega16
IC2: ATtiny44
IC3: 74HC139
IC4: LM358
ICs are sensitive to electrostatic damage!
Electrostatic sensitivity means that these electronic parts can be destroyed
only by being touched by an electrically charged person. A person can get
electrically charged e.g. by wearing clothes of fleece material, or by walking
on a carpet. By touching grounded metal the person can easily get
discharged.
