Printed Circuit Board for PS/2 Wheel Mouse Controller
There is a reference PCB design, done by Marc SAVART [sil51#ifrance.com]. It is designed
for use on A4000T (also you can see
photos archive of
ready device). I can't give any warranty for this PCB design, but now I manually check
every version for wrong connections :)
This is a completely new design. Main feature of this design is that is ONE PCB
for all versions of hardware. It is «configured»
by wires. You can for example do PCB for 5-button version with existing PIC16F84 (in
socket of course), and then buy PIC16F627 and upgrade PCB to 2-wheel version.
