It arrived well packaged and in good condition. Good value for money.
Pontosan úgy, ahogy leírtuk, cserealkatrészként fogjuk használni, ha a motorral egy időben megrendelt baleset történik.
The quality of the Motor Driver is good. The quantity was also correct. Unfortunately, one was already broken. Nevertheless fair price. Good product for little money. Thanks.
These are 1.5A stepper drivers. The current sense resistors are R10, or 0.1 ohm. The formula for calculating the AMPs is: Amps = VREF / (8 * senseResistor). So to get 1.5A, set the pot to 1.25V. 1A would be 0.8V.
but a little tricky. DO NOT unplug your stepper motors when they are powered. They will be killed. Otherwise they do what they have to do. Good bargain
Lieferung ok, wie bestellt, Danke
super
Nagyon hasznos
pontosan mit vártál volna
