Re: Single axis tb6560 board from ebay - evaluation
The TB6560 has been around for a while, but it is very far from reliable in almost all the Chinese manufactured boards. They ALL suffer the same layout, lack of noise immunity, and design issues, and as James pointed out, by design they have a very specific power up/down sequence, which makes them subject to very commonly blown drivers.
And most of the ones I've seen that have isolation inputs usually are wired with this bypassed. Noise of course is another matter altogether that many, many, people have struggled to fix with these drivers.
In short, they're garbage in most instances. Even after others have done the multitude of board re-wiring to get them functional, they are still a very low powered board.

It's rumoured that everytime someone buys a TB6560 based board, an engineer cries!
