AVR microcontrollers can use either built-in (internal) or quartz-crystal external clock for
the purpose of providing clock signal source. The EasyAVR
crystal socket for all microcontroller sockets. DIP40A and DIP40B sockets are directly
connected to quartz-crystal socket unlike DIP28, DIP20A, DIP20B, DIP14 and DIP8
sockets which are connected to it through the pin jumpers (J13-J17). The value of the

IMPORTANT:
How to properly place your microcontroller into the DIP socket?
Before you plug the microcontroller into the
appropriate socket, make sure that the power
supply is turned off. Images above show how to
correctly plug a microcontroller. First make sure that

a half circular cut in the microcontroller DIP packaging
matches the cut in the DIP socket. Place both ends of
the microcontroller into the socket as shown in Figure

quartz-crystal depends on the maximum clock frequency allowed and your application
as well. You can always replace the default 8MHz crystal with another one. If you want to
use microcontrollers in DIP40A and DIP40B packages, it is necessary to place jumpers
J13-J17 into the I/O position, Figure 4-5.The position of jumpers for DIP28, DIP20A,
DIP20B, DIP14 and DIP8 sockets is shown in Figure 4-6 to Figure 4-10.

all the pins match the socket as shown in Figure 4-3.
Check again if everything is placed correctly and press
the microcontroller until it is completely plugged into
the socket as shown in Figure 4-4.
