Schematic

Good schematics checklist

Good schematic checklist

Refer to the correct datasheet version number and the last updated date for the component
Separate double wire junctions
Use dots for wire junctions, not crosses
Make symbols for similar devices consistent E.g. resistors
Name every part with a unique designator
Align wires and components horizontally or vertically
Label pin numbers on the outside of a symbol, signal names on the inside
Place text orientation consistently E.g. horizontal
Place components from left to right with a logical flow
Put higher voltage towards the top
Put positive voltages Vcc up and negative voltages GND down
Separate schematic into logical blocks
Make the schematic fit in A4 or A3 standard sized papers
Place decoupling capacitors next to their devices
Keep names reasonably short
Use uppercase symbol names
