They claim that this will run 60V and high amperage. It will not. I purchased a couple of these earlier this year and finally got around to using them. I intended to use them for a 6 axis robot, with NEMA 34s, which require the higher amperage. I hooked everything up according to the guide. The lower amperage NEMA23s I used on the upper arm ran just fine. The NEMA 34s made a pop, and then the driver section of the board died. That's over 100 bucks down the drain. Note that these same motors work just fine with real stepper drivers. If you intend to use this board for higher amperage for 3D printers/ CNC/ robotics applications, look elsewhere. It sounds too good to be true because it is. Read more

The board works great! Very powerful board, great for up to 48V stepper motor control. Integrated stepper motor controllers. The BTT documentation is just downright awful. There doesn’t appear to be much in support from the manufacturer. The manual hasn’t been updated in over a year. I had to supplement my documentation with documentation from some of BTT’s other boards to piece together enough information to configure the board. Because the lack of documentation, there aren’t many people running these boards. As a result, community support is hit or miss. Don’t buy this unless you can be patient as configuration will take quite a while. Also don’t buy unless you’re confident enough with your technical proficiency to dive deep into Linux configuration and killer configuration without much support. Read more

Great board but s1 to s4 uses larger connectors and you will need to double over the wire. If you don’t the possibility of a weak connection will happen. You will have weak continuity and appear to have a failed motor or driver. These are the only bothersome connections. Board is great otherwise. There should be an adapter for the larger connectors to mate with smaller wires for nema 17. Used on my Voron build. Canbus works but usb appears more stable. Onboard power for pi is not enough if you run a large touch screen and pc HD web cam. I have 100 leds on the frame running on the same port and no issue. Don’t forget art to pi means no canbus. Wish the called this out in bigger writing. Also wish they had a generic 48v config vs 24v.BTT should clearly call out the sense resistor in the manual and not just the generic config. This board has lots of option just the 5v is not enough for a hungry pi. Read more
