I'm new here, and after doing a search for Eprom programmers I came across this site. I am going to build my own board using the circuit diagram for the Dual Power version. I am using Kicad to lay out my circuit and board, but I have come across an issue that I was hoping you could clarify for me.
On the circuit diagram there are power points labelled VPP and Vcc1 but no where on the diagram does is show where these supplies come from. The Vcc obviously is supplied via the 7805 Voltage Regulator. Also where in the circuit is the USB connector?? It's plainly on the picture of the board that I have saved but not in the circuit. Could any one clear this up for me???
Thanks
