Himm, dispite the documentation saying
Mosfet group Mosfet name Controlling pin Output connector Input method Voltage Current
Small mosfets First small mosfet 2.4 X7 Small mosfets power input X6 12-24V 3A max
Small mosfets Second small mosfet 2.6 X8 Small mosfets power input X6 12-24V 3A max
It looks like if I apply 5v to power in 2, then both small mosfets can pwm 5v...
