Sup there thanks for info i would like to include a onboard controler but i need a schematic for the minimum of parts the controler that are needed to run ,im on a electronics colage so my teacher can etch my pcb's
It will be fototransfer and i will solder them my self
Nice! Photo transfer is the best method for hand-made PCBs. If you have problems to produce double-sided PCBs, try using some jumpers - pieces of wire soldered at the top of the PCB, as if it was the top copper layer. Just don't abuse them, or your board will be ugly and difficult to solder.
As for the microcontroller schematics, you can see
the schematics of the GH60 revision A. Although it uses ATmega32U4 mcu, it is easy to adapt it to the ATmega32U2.
On my last post I linked Atmel's pages about the ATmega32U2 & ATmega32U4, you can download the datasheet of them there. Read them, it is very important.
Could you tell me where can i get the lovest cost switches and keycaps ?
The keycaps I bought at
WASD, but it isn't the cheapest option available. You can also buy blank keycaps at
Pimp My Keyboard.
Switches: try to find someone who sells Gateron switches, they are good and cheaper than Cherry MX.
And finally: ATmega32U2 is cheaper than ATmega32U4, but both are not that expensive. Use the one you find easier to find/use.
