Maximum allowed current on each pin is 3A.
Available cable kit:

Fan Connector (Fan)

7.2
The Fan can be used to actively cool the heatsink mounted on the board. The fan rotation speed can be
monitored and the fan speed controlled by the temperature of the PCB (near SoC).
Signal Description
PWM PWM output signal for FAN speed control.
TACHO Tacho input signal from the fan, for rotation speed supervision RPM (Rotation Per Minute). The
signal shall be generated by an open collector transistor or similar. Onboard is a pull-up
resistor 2K2 to +3.3V. The signal has to be pulsed and onboard circuit is prepared for two
pulses per rotation.
