RioRand 350W 6-60V 3-Phase PWM DC Brushless Motor Speed Controller with Hall Sensor – for 120° Electric Angle Brushless DC Motors, DIY Robotics, Electric Tools & PLC Systems

These motor controllers work well with big DC motors. You can only run one motor off of each one. You do not have to use all of the pins to control the device with arduino or esp32. R_ls and L_ls can be left with no connection. The enable pins can simply have 5v applied directly or can be switched. The only thing that might be of concern is the heat sink is on the other side of the board from the mosfets. I really don't think that they will dissipate any heat the unit heats up under high load.

Used on a hoverboard motor and works well.

So far it works well. I need to address the direction control on the Hall model. The motor will run in a couple different phase wiring orders, if you have it in the wrong order the reverse direction switch does not work. Once you fix that, it reverses perfectly.

This controller ran great out of the box for me. It drove a 24V 6A motor with ease. No heat issues and high torque. If you're going to use the PWM mode to control the speed, make sure you remove the jumper next to the speed pot on the controller board. If it weren't for a couple of gotchas, I would have given it 5 stars. Gotchas: The controllers power down in PWM mode after a few seconds connected to +5V power, and then they don't re-enable. It seems that the PWM channel is very sensitive to noise and so something causes the controller to shut down. I could "wake" it back up by wiggling the wire connected to the +5V power to the controller. If you are using an Arduino, instead of connecting the 5V terminals on the controller to a +5V power source, connect it to one of the Arduino's digital pins instead. These pins are at TTL logic levels (+5V) and they provide enough power to supply the logic on the controller. You can then toggle the pin on and off to enable and disable the controller. When the motor is stopped or you want to stop the motor, set the pin to LOW so it clears the controller of any internal shutdown mechanism. When the motor needs to move, set the pin to HIGH and the controller logic will power up and resume. The brake isn't really a brake. It just cuts the power to the motor and has no holding torque. There's no power that goes to stop any momentum from the motor, so the motor stops itself through friction. This is way cheaper than a lot of controllers out there and I think it's a great value for prototyping mechanical setups without having to spend much money!

Really simple and good to use
