IC2 |
: |
The melody IC of the 3 terminals is used. There is possibility that the connection of the lead line of the component depends on the kind. |
|
L1 |
: |
The coil, capacitors are OK near the rule value. There are parts which the obtaining is difficult for. |
|
Xtal |
: |
It uses the one from 9 MHz to 10 MHz. It becomes the electric wave which goes out of the transmitter by these 9 times. |
|
PCB |
: |
Make the original PCB. Production |
|
Multilayer ceramic capacitor |
: |
I used the Multuilayer ceramic capacitor in the relation of the lead line in the interval. |
