new product:

The TMCM-1110 is an universal ultra low cost stepper motor controller/driver module. The driver part offers highest smoothness and precision due to a high microstep resolution and the new patented spreadCycle™ chopper scheme for optimized current -zero crossing and -sine wave form. The integrated sensor less load detection stallGuard2™ and the load dependent current control coolStep™ make this board unique. This features make it the first time possible to drive a stepper motor energy efficient! http://www.motioncontrol-community.org
