Stepstick TMC2208 V1.2 driver Stepper Motor Super Silent With New Heat Sinks Replace TMC2100 For 3d Printer Parts

Model: TMC2208
Drive current: 1.4A
Peak current: 2A
Voltage range: 4.75V-36V
Subdivision: 256
Additional functions to TMC 2130: 
SPI configuration interface (up to 4MHz)
Up to 256 native microsteps (no interpolation)
Coolstep - energy saving current control
Stallguard2 sensorless motor load detection
Buck - depend on the speed control of the load
Drive Current Algorithm and Adjustment: 
1, Drive Current Algorithm: i=Vrefx1.9/2.5, the default Vref is about 0.65V, so the default current is 0.5A, maximum current is 1A.
2, Vref measure Gnd and potentiometer middle voltage.
3, Make sure not to connect the motor when measuring voltage, otherwise driver will burn out.
4, Connect to power when measuring voltage, don't just connect USB for power supply.
5, Please pay special attention to direction, do not insert wrongly.
Instructions: 
1. When used on Ramps1.4 or MKS Gen, please remove the 3 jumpers under socket.
2. Pay attention to direction, do not insert wrongly.
3. Heat sink directly attach on the PCB.
4. The motor direction is opposite to that of 4988 and 8825, please adjust the firmware or adjust the motor wiring if you want to replace 4988.
