Core Fan Header

• The Fly Pi Fan header supplies +5v for a CPU cooling fan.

VCC header

• Supplies line level voltage

CAN Hat

• The red pins of CANHat correspond to the blue female headers of FLY-Pi, and the black ones correspond to black (inserting them backwards will short out the CANHat)
• The CAN interface of FLY-Pi has an incorrect silk screen, please connect according to the figure below.
