2.3.5 Ceramic plate capacitors
The four ceramic plate capacitors C1, C2,
C12 and C13 have a capacity of 22 pF
(imprint: 22). You don't have to pay
attention to the polarity.
2.3.6 Crystal
The crystal Q10 has a frequency of
15,000MHz. After positioning the housing
should not be in contact with the board
(Optimal distance to the board: 1mm). You
don't have to pay attention to the polarity.
Tip: It helps to put a 1mm thick piece of cardboard between plate and crystal
before soldering. After the crystal is soldered the cardboard can be carefully
removed.
2.3.7 IC-socket
There are four IC-sockets to be soldered
onto the board. The 40 pin socket is for the
main controller ATmega16, the 14 pin
socket is for the ATtiny44, the 16 pin
socket is for the demultiplexer 74HC139
and the 8 pin one is for the operational amplifier LM358.
The notch in the socket must point in the same direction as the mark on the
board. The ICs will be inserted later!
2.3.8 NPN Bipolar-transistors
The four NPN bipolar-transistors T4, T5, T8
and T9 are of the type BC337. During
placement you have to pay attention to
the polarity! The flat side of the transistor
is marked on the circuit board.
Hint: The transistors are not mounted flush on the board, they have to be
