I have decided to break into the PIC world for my latest project (calculating rotational speed with a quadrature encoder) that is probably going to require a PIC18F2331/2431/4331/4431. I would like to cut the learning time down by using some sort of kit, either preassembled or containing all the necessary parts. Is there a generic PIC18F kit that would work? I saw that the PICkit 3 Debug Express comes with a development board with PIC18F45K20 on it. Can I desolder this PIC18F45K20 and replace it with my PIC18F2331/2431/4331/4431?
