TMC429 - TRINAMIC

TMC429 Intelligent Triple Stepper Motor Controller

The TMC429 is a miniaturized stepper motor controller with an industry leading feature set. It controls up to three motors via SPI or Step/Direction interface. The SPI interface provides a programmable 6 bit microstep table (64 µsteps / fullstep) for best step accuracy with 2-phase stepper motors. Based on target positions and velocities - which can be alter.
