2PCS TMC2208 V1.2 3D Printer Stepper Motor Driver, Upgrade TMC2208 Stepper Driver Module with Heat Sink Screwdriver for 3D Printer Controller Mother Boards Reprap MKS Prusa i3 Ender-3 Pro

• TMC2208 is an ultra-quiet two-phase stepper motor drive chip, continuous drive current 1.4A, peak current 2A, voltage range 4.75V-36V, 256 subdivision.
• The flexible microPlyer interpolation unit provides up to 256 subdivisions, allowing perfect sinusoidal control even in systems with limited pulse frequencies; these are also designed because stealthChop2 ultra-quiet technology is widely used in 3D printing.
• Compatible with existing 3D printer electronics, eliminating the expensive costs of redesign. It can replace the original TMC2100 A4988 DRV8825 LV8729, lower heat, especially for 3D printing market.
• With this adapter you can test your SilentStepStick or flash the TMC2208 SilentStepStick with an USB-to-serial converter.
• The adapter comes with stackable headers, so you can use it direct on your 3D printer board. The tester is pre-configured for standalone operation on an USB to serial adapter (VIO-VM jumper closed).

Specifications: Interface: Step/Dir Configuration: CFG Pins or UART Native Microsteps: up to 1/256 MicroPlyer Microsteps: 1/256 Logic Voltage (VIO): 3-5V Motor Voltage (VM): 4.75-36V Motor Phase Current max: 1.2A RMS, 2.0A Peak. Therefore, the reference voltage of the driver module should not exceed 1V. At the same time, the driver module must be dissipated, otherwise it will affect the life of the driver module. Note: TMC2208 driver needs extra fan to cool it, otherwise the high temperature may destroy it. Do not connect the motor when measuring the voltage, otherwise it is easy to burn the driver. Power should be connected when measuring voltage, do not just connect USB power supply. Package Includes: 2 X TMC2208 Driver 2 X Heat Sink 1 X Screwdriver
