HW-517 as a H-Bridge

Hi, I want to use 4x HW-517 as H-Bridge to control a brushed motor. The PWM signal comes from a Flysky receiver ( rudder CHannel 1) . To feed the 4 x HW-517 I want to use a Arduino Nano. PulseIn to measure the pulse width and use analogWrite to trigger the 4x HW-517.

Is there anyone with experience on this subject. Is this possible considering the hardware and especially the code worries me in the timing. The brushed motor can’t be switched backwards to quickly.

Considering the hardware, it is not possible.
Q1 and Q3 would require special (high side) drivers, extra transistors

Cheaper and easier and smaller to buy a motor driver.

What is your motor voltage and max current?
Maybe we can suggest a driver that will work.

Thanks for your response. I see now It is not possible. I am going to try using an ESC with reverse.

That would make sense
