DAOKAI BTS7960 Motor Driver Module 43A High Power Double DC Stepper Motor Driver Module H-Bridge Semiconductor Refrigeration PWM Smart Car Driver Module, for Arduino

This is a reasonable motor control module. It’s easy to use as there’s enough information in the listing to get you going.Heatsink placement feels a bit odd; I’d have thought it would be better to be stuck directly on the chips.

DAOKAI BTS7960 Motor Driver Module 43A High Power Double DC Stepper Motor Driver ModuleThis is a module for the hobbyist who wants to control it from an Arduino, Raspberry Pi etc. and can be used for a variety of things.The module comes with a ribbon connector to fit the socket, a heatsink, and two screws to fit the heatsink to the PCB. Be careful you don't lose the screws. I'd suggest that you fix the heatsink straight away, or put the screws in the heatsink holes until you're ready to use it.Rather than the heatsink fitting '/ sitting directly onto the component, for what is normally the best heat transfer, the heatsink fits onto the underside of the PCB and the heat is transmitted from the component, through the PCB, then to the heatsink. I don't know how effective this is if there is a lot of heat being given off.The connection point details are marked on the PCB. There is no information provided with the driver module, such as how to fit the heatsink (easy to do), specifications etc. Information is provided on the listing page, but make a note of it in case the page disappears.The module appears to be good quality, with no obvious solder flaws. There is a screw hole at each corner for mounting. It is best to use this module mounted on spaces, even temporarily, to avoid shorting out any of the contacts on the underside of the board.

My project was delayed by several weeks due to me not noticing that my motor driver is faulty where the PWM pin controller was fried and faulty, this caused a lot of hassle and time wasted and I am not happy

They work well with no problems .
