General Design rules

• Power symbols facing up.
• Pull up resistors face up, pull down resistors face down
• GND facing down
• Labelling/defining connections
• leave notes on what you’re implementing
  • example: task for breaking out i2c to a header pin
  • example: add decoupling capacitors for all power pins of an MCU

Design for mechanical considerations

• Add mounting holes (in Kicad under MountingHole_Pad)

Design Tips for smaller (single sheet) designs

• Organize component groups with dotted line boxes
