Expansion board for independant stepper motor drivers (57/86 stepper drives) Built in buffer chip (type 74HC04) Ideal to connect your MCU to any high current stepper motor drives This module is compatible with standard A4988, DRV8825 etc... stepper motor drivers pinout
This pack contains 5 NEMA17 stepper motors compatible with Scalar 3D printers. Powerful, robust, with a nice capacity to stay cool thanks to it's 40mm high and limited 1.2A per phase; Uses only 1.2A for a 4000 g.cm torque (0.44 Nm ou 62 Oz.In) It contains: 5 motors with 1m lead wires and a 4 pin female dupont connector
Allows to drive Stepper motors. Max coil current: 2.2A More powerfull and more precise than the commonly used A4988 Needs a good air flow below the chip THe heatsink is optional if you have a good air flow, but needed in order to use the max current. Maximum resultion of 1/32 micro-steps supported by 8bit micro-controlers such as Atmega 2560.
