12V-24V-48V-110V-Dc-motor-Controller-PWM-speed-regulation-MACH3-spindle-speed-Control-xj.jpg

I can find very little documentation

but one aliexpress seller link does say "the PWM input requirements as follows: 3.5 12 v VPP level,"

Wich im guessing is 3.5v to 12v levels...

So 3.3 might not be enough...

Its a 48v spindle so can't be directly connected to smoothieboard MOSFETs

Thoughts or ideas?

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...
