TMC2208 V1.2 Stepper Driver Module with Heat Sink Screwdriver for 3D Printer Controller Mother Boards Reprap Ramps1.4 MKS Prusa i3 Ender-3 Pro
3D Printer Stepper Motor Driver
MC2208 V1.2 is an ultra-quiet two-phase stepper motor drive chip
continuous drive current 1.4A
peak current 2A
voltage range 4.75V-36V
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
TMC2208 V1.2 driver needs extra fan to cool it, otherwise the high temperature may destroy it.
Don't 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.
