T- Module Stepper Motor Driver Controller Board Ultra Silent with Heat Sink for Arduino 3D Printer(TMC2100 Pack of 4)
Size: 20 x 15mm / 0.78 x 0.59"
Max. Current: 1A
Drive Current Algorithm & Adjustment:
1, Drive Current Algorithm: i=Vref*1.9/2.5, 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.
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.
