DC5-12V 0A-30A Dual Channel H Bridge Motor Driver Board Module Robot Stepper Driver Controller Board Module for Coreless Motor for Toy Cars DC Motors

Using this controller to drive a high output fuel pump from a 24kHz PWM control signal is 24kHz.35amp inrush on startup, and 12-18 amp continuous operation, the driver is going strong and within reasonable thermal limits. Nice value for the cost.

This DC 5-12V Dual Channel H Bridge Motor Driver Board is a fantastic choice for controlling DC motors in robotics projects. The dual-channel design allows you to control two motors independently, and the wide voltage range (5-12V) makes it compatible with a variety of motors. The 30A current capacity is impressive, providing ample power for even demanding applications. I've been using it to control the motors on a small robot, and it's been working flawlessly, providing smooth and precise control.

No manual no datasheets, guess and hope for the best right???

I connected up both channels. One uses about 5A, the other can draw up to 30A. The 5A channel works perfectly. The 30A channel burned out that side of the H Bridge immediately.

The media could not be loaded. I used this to make a breathing machine for testing intra-nasal devices. I needed to run a linear actuator with an arduino and a Nextion HMI, and this did the trick. It comes with zero technical info though, so I took off a star. Basically in order to use it, I used the Easy Nextion library, made my interface first. I declared the pins I would use on the arduino, and did some math to make it work out. I declared pins 10 and 11, and used the header on this board with ground, In1 and In2 connected to the arduino. Works great!

Had some trouble getting 3.3v PWM from my ESP32 to register on the driver but I fixed it by using the MCPWM library pre-built into the ESP32 and setting the PWM frequency to 24000Hz. Unfortunately, literally none of the screw terminals worked so I just clipped them off and soldered my own connections. Other than that the product works fine; did not test the 30A claim.
