Arduino Stall Guard SHIELD
Arduino SHIELD with 5Amp. Micro Stepper Drive and integrated STALL-GUARD that predics stalling of the motor without the need of a shaft encoder. Up to 4 axes can be controlled with a single Arduino CPU module. The CNC-Controller interfaces with Opto Couplers of this shield to prevent noise and ground loops.

Arduino Micro-Stepper SHIELD
Drives with STALLGUARD option are available now with the widely adopted ARDUINO footprint. These drives predict stalling of a step motor and can do that without the need of an encoder!
More important: hobby developers as well as professionals can jump-start to using the OpenSource EMC2 controller and have direct access to 5-Amps Micro Stepping up to 4-axes with a single Arduino CPU module.
