Features No Noise: This stepper motor driver continues the characteristics of TMC series drivers, and has a good mute effect. Support UART Mode: The driver supports UART mode and is applicable to for MKS SGEN L without jumper. Large Current: The drive current is larger, the maximum peak current is up to 2.5A, and the stable printing current is up to 1.7A. Good Heat Dissipation: This stepper motor driver has lower heating efficiency and better heat dissipation than other TMC series drives. 256 Subdivisions: The chip of the driver is expanded to 256 subdivisions internally, with better performance.
