Teyleten Robot BTS7960 43A High Power Motor Driver Module/Smart Car Driver Module for Arduino Current Limit 2pc

Worked beautifully. One catch though. Both LEN and RLEN need to be enabled for the driver to operate.

I have been using this little motor controllers for awhile now, and I've purchased dozens. In the past, I've complained that about 7 out of 10 work, so I always buy extra. But lately, I have noticed all of the controllers have been working. Also, I complained about the pins getting bent during shipping, etc, but these have extra packaging to prevent the pins from getting bent. I'm very happy the supplier listened to the reviews and improved the entire experience. Thank you so much! 3.24.2024 - Update - I upgraded the motors on my project from 24V 280W DC Motors to 24V 350W DC Motors. The new motors claim to need ~18amps of current. These motor controllers 'blew up' immediately. I knew they weren't really going to handle 43amps, but I was hoping they would work with the new motors. Now I need to research an alternative.

All of these controllers came burnt out, despite running mini tests on both I could not get them to function, and after turning to the Internet, I found out that this was a common problem for these models. I would not recommend. I hope they can resolve their manufacturing issues because I really needed these for my project.

Good motor drivers. Work flawlessly.

Wish documentation was provided here, but it does seem to have decent built in protections for reverse polarity (I accidentally plugged the battery + into - and vice versa). You need to provide vcc with 5 V, gnd with ground, R_en and L_en are enables for the left and right and are active-high signals with a default value (pull down resistor I presume) to ground meaning they are by default NOT enabled and not able to be driven. For my purposes I just tied R_en and L_en to HIGH which logically works with 3.3 V as well although i do believe it works with 5 V that way whenever I try to drive right or left they're already enabled, however I assume you could tie them to digital pins and enable/disable right/left depending on what you need driven. the PWM signal also works with 3.3 V and 5 V for high believe. The 43 A being listed in the title is a little misleading since this is the absolute max and you absolutely do not want your continuous current to be anywhere close to this. I'd likely keep it below 5 amps
