Do we know anything about it? The listing is light on info.
Looks like it might be this going by the ‘NMOS’ GitHub - ChenDMLSY/N-MOS_-FOC-DualMotorDriveBoard: 该驱动板是全N－ｍｏｓ的FOC双路电流环驱动板，超高性价比！资料分享！
Yeah, nice find!
Looks like someone’s driver board, being advertised as SimpleFOC compatible. Its not an “official” product or anything like that, and I can’t say if or how well it works… you’ll have to order one a try it out
If you do, please post your experience here, that would be very kind!
