Review on 🔄 KNACRO PWM to Voltage Converter Module: 0-100% PWM Converted to 0-10V Voltage for Signal Interface Switching in PLC or Industrial Control Applications (PWM-to-Voltage) by Cesar Carter

Did everything according to specs to try it with a 5V PWM input powered by a 24V DC power supply to get it running. No matter what I tried (changing the frequency in my grbl stm32 firmware to 1kHz, 2kHz, 3kHz, even up to 100Hz, I still stuck to max 10V output). I ordered another board from Amazon and it immediately worked as it should, so I would refrain from using this product to convert PWM to 0-10V analog voltage for VFD spindle speed control. Too much time wasted troubleshooting this product even though I used an oscilloscope to analyze my PWM signal which was perfectly fine.
