Suggestions from a frequent user (1/2) It's trivial stuff, but usually untold In schematic drawing Make drawings small, or you'll use up too many pages (hard to manage) Default resistor, inductor, etc may be too big: make yours Use smaller-than-default text: 0.04 or 0.03 inches is best Use labels rather than wires, so you can change pins while routing Add diagnostic leds for your microcontroller Always include a power-on led If it fits, add self-test circuitry Be generous with 0R resistors for options and tests Be generous with 0R1 or 1R0 resistors as current-meters
