Stepper motor's driver based on the system DRV8825, allows you to control the motor with a current consumption of up to 1.5 A (with cooling of up to 2.2 A) per coil, at powering with the voltage of up to 24 V. The module with the goldpin leads and the attached radiator.
Stepper motor driver based on the A4988 system. Voltage supply in the range of 8 to 35 V with maximum current consumption of 2 A per coil. Maximum resolution: 1/16 of a step. The module allows for current flow up to 1 A without a radiator.
Stepper motor driver, power voltage range from 6 V to 35 V, with maximum current consumption of 3A through the coil. The maximum resolution is 1/128 step. The module allows a continuous stream of up to 1.8 A current without a heat sink. Digital communication and through the SPI bus.
