Need schematic diagram and code for driving NEMA 17 stepper motor at high accuracy RPM (configurable between 1-10 RPM).
Must use TMC2208 silent driver and be corrected by real time module.
Must use Arduino Nano USB-C. Powering should be 5V via USB.
The stepper motor will drive clock gear train and thus the requirement for the RPM accuracy.
How much do you want to pay for this work ?

What would this module be? And how do you intend the correction to be made? The clocking could be fast or it could be slow and when would you make the adjustment?
Dronebotworkshop has stepper accuracy to less than a degree, which could translate to RPM accuracy.
You say you want "high accuracy RPM" but still don't state a tolerance of this accuracy. How is the programmer going to know when they've achieved what you want?
Accuracy would presumably be achieved using real time clock interrupts. How many steps per revolution of the stepper motor do you plan to use and what is the maximum rate?
