DollaTek 5Pcs Stepper Motor Driver TMC2208 for 3D Printer Motherboard Packed with Heat Sink and Screwdriver

• The latest version of the TMC2208 V1.2 takes the UART out and uses the UART function directly, eliminating the need for more wiring.
• The microPlyer interpolation is with 256 subdivisions,which allows perfect sinusoidal control at limited pulse frequencies and faster motor acceleration/deceleration.
• Compatible with most motherboards of 3d printers in markets, which can replace TMC2100 A4988 DRV8825 LV8729 stepper drivers.
• Two-phase stepper motor drive chip, continuous drive current 1.4A, peak current 2A, voltage range 4.75V-36V.
• CoolStep current dynamic adjustment technology, which saves 70% energy; dcStep ,stallGuard2 stall detection technology ;Automatic standby current reduction.

Features Interface: step/dir 1. Configuration: CFG or UART pins 2. Native Microsteps: up to 1/256 3. MicroPlyer Microsteps: 1/256 4. Logic Voltage (VIO): 3-5V 5. Motor Voltage (VM): 4.75-36V 6. Maximum motor current. : 1.2A RMS, 2.0A Peak Therefore, the reference voltage of the control module should not exceed 1V. At the same time, the driver module must be dissipated, otherwise it will affect the service life of the module. 7. Internal V regulator: activated 8. RDSon: ≤0.3 Ohm. 9. StealthChop (silent): yes 10. SpreadCycle: yes 11. MicroPlayer 12. CoolStep: No 13. StallGuard: no 14. DcStep: no Note: 1. The TMC2208 driver needs an additional fan to cool it, otherwise high temperatures may destroy it. 2. Do not connect the motor when measuring the voltage, otherwise it is easy to burn the driver. 3. The power supply must be connected when measuring voltage, do not just connect the USB power supply. 4. Please pay special attention to the instructions! Package includes: 5 x TMC2208 Driver 5 x heat sink. 1 x screwdriver
