I'm using stepper motor for an application that requires the motor to be extremely silent. (not 3D printing) So I found out that the TMC2130 driver (or TMC2100) does just that. In my research of specs between drivers and motors I've gotten pretty confused. I've come down to using the TMC2130 to drive a Sparkfun ROB-13656 stepper motor. Before I purchase I want to make sure the voltage and current ratings of both will work together.
The TMC2130 says it supports stepper motors up to 2.0A coil current (2.5A peak). The ROB-13656 says 2.0A/phase. Is that the same thing as coil current?
The TMC2130 says it has a voltage range of 4.75-46V DC. And the ROB-13656 says Voltage: 3.2V. I know these specs don't correlate since the driver is monitoring the current, but I still don't really understand how they relate to each other.
