TMC2208-LA stepper motor driver chip; Number of axes: 1; motor type: 2-Phase; rms current: 1.4A; working voltage: 5V~36V; highest subdivision: 256; control interface: S/D + UART; smooth operation; mute technology; Microstep interpolation， for 3D printers.

The TMC236 is a low-power, two-phase stepper motor driver chip that supports SPI communication and a full range of protection and diagnostic functions. The built-in high-efficiency MOSFET provides a high-performance external drive with a drive current of 1.5A and can operate in an external high temperature environment. The TMC236's low pin count and high performance make it the best choice for embedded motion control systems.
