Gallery : IC socket for wire wrapping
[caption id="attachment_405" align="alignnone" width="300"]
This is IC socket for wire wrapping.
18 pin type.
18 pin is PIC16F84A CPU in our circuits.
Wrap wrapping wire to these pins.
No soldering, wire wrapping is safety against heat.
3.3 Volts IC and 5 Volts IC, both is O.K.
We still did not make another board.
But PIC16F84A CPU all pins are connected to out side of CPU board through Direct Bus.
You can make many circuit board, ex) LED test board, by your own, in out side of CPU board through Direct Bus.
We can not port/translate all PIC16F84A circuit boards in all of the world.
You can make PIC Writer board in out side of CPU board through Direct Bus too, this circuit image is in us too.
You are free, we are free.
You have your rights, we have our rights.
We selected 3.3 Volts with 2 batteries, but 5 Volts from AC-DC Power Adaptor is a good too.
Please enjoy your circuits.
We made Direct Bus for you and for us.
If you want to use removable IC sockets, you can.
If you want to make our circuits on braedboard, you can.
You are free.
Please do not be afraid of digital circuits.
