For example, for a motor with a resistance of 5 Ω per coil and a current consumption of 1 A, the nominal supply voltage is 5 V. To do this, limit the maximum current draw using a potentiometer, so as not to exceed the allowable motor current. The circuit can be used to control motors with a nominal voltage lower than the required 8.5 V. The motor supply voltage from 8.5 V to 45 V is applied tothe VINpin. The figure shows the minimum connection of the controllerĪ comprehensive user guide is available from the manufacturer.Ī 5V regulator is required to supply power (no external logic supply is required) tothe 5V pin. If the nominal motor voltage is lower than the required driver supply (8.5V), set the current limit manually using the potentiometer. To control a bipolar stepper motor connect the system according to the diagram below. iNode - sensors and modules Bluetooth Android.
