Compared to the tmc2100 stepper motor driver module, the tmc2208 driver module has lower heat. The heat of tmc2208 at 0.8A has the corresponding effect as the heat of tmc2100 at 0.5A, and can be used interchangeably with tmc2100. Supports uart mode, you can use uart mode in mks sgen l v1.0/mks gen l v1.0/mks gen l v2.0/mks robin, skr 1.3/1.4 by setting the jumper cap. (No jumper needed, no welding of the driver required, and it is more convenient to use). This function does not support mks gen l v1.0 Tmc2208 single-axis stepper motor drive circuit, standard current: 1.25a, maximum current: 2.0a, input voltage: 4.75v-36v Step resolution: 256 microstep/step resolution. Flexible micro-plyer interpolation unit, even limited in pulse frequency system can still be perfect to achieve sinusoidal control. With patented technology spread cycle high chopper frequency, dcstep, stall guard2 stall detection technology, cool step stream dynamic adjustment technology, can save 70% energy, stealth chop mute technology.
