I am drafting in KiCAD ANOTHER project(I need to finish some of them one of these days.), which is a Propeller 1 form factor designed to snap into a BASIC Stamp 2 family socket. My questions are:
Which regulator should I use to bring Vin down to 3.3v?
How should I make a transistor-based(or resistor based) voltage shifter for the I/O?
Can I use the programming pins in the stamp socket for programming the prop?
Is this just absolutely preposterous?
