Descriptions:
Flexible microPlyer interpolation unit, the component can provide up to 256 microsteps/step resolution. Even in the limited pulse rate system, it can still be able to achieve sinusoidal control. Because stealthChop fine sound technology is widely used in 3D printing, these components are also designed to be compatible with existing 3D printer electronics, saving the need for costly redesign. Both components have pulse/ direction input, and it can be completely independent operation. The configuration is implemented via digital input.
Based on TRINAMIC TMC 2100 two-phase motor, stepper motor drive board, TRINAMIC TMC 2130 or TRINAMIC TMC 2208, it is compatible with stepstick and pololu a4988 hardware.

Features:
SpreadCycle high chopper frequency, dcStep, stallGuard2 stall detection technology;
CoolStep current dynamic adjustment technology, it can save 70% of the energy, StealthChop mute;
TRINAMIC stepper motor driver (chopper drive/ constant current drive);
Automatic standby current is reduced;
Microplyer – subdivision interpolation and smoothness increases;
Mtealthchop – quiet operation and smooth action;
High dynamic motion control chopper;

Specifications:
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
Automatic stealthchop and spreadcycle switching depends on speed

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.
