How to Interface a 4-Wire Vacuum Suction Motor from a Vacuum Robot with a Raspberry Pi?
If you look at the 2nd picture, it is marked as VCC, GND, PWM and *fg. I tried with first 3 pins and gave rpi pwm but didn’t work. I think the 4th one is enable pin. But tried supplying 3.3v constant on both pwm and enable bot that didn’t work. Assuming most BLDC are 5v, I tried 5v as well and that didn’t work.
