A. Comparing with the TMC2100 driver module, the TMC2208 driver module tends to generate less heat. The heating effect of the TMC2208 at a current of 0.8A is approximately equivalent to that of the TMC2100 at a current of 0.5A, and it can be used interchangeably with the TMC2100. B. It supports the serial port (UART) mode. You can use the serial port mode on MKS SGEN L v1.0, MKS GEN L v2.0, and MKS SKR 1.3/1.4 by setting the jumper cap. (No need for jumpers, no need to solder the driver, which makes it more convenient to use.) This function is not supported on MKS GEN L v1.0. C. The TMC2208 is a single - axis driver chip with a default current around 1.25A, a maximum current about 2.0A, and an input voltage ranging from 4.75V to 36V. D. Stepping resolution: 256 micro - steps per step. It has a flexible interpolation unit that can achieve sinusoidal control well even in a system with limited pulse frequency. E. It has patented technologies, including high chopping frequency, DC step (dcstep), stall detection technology (stall guard2), dynamic current adjustment technology (cool step), which may save about 70% of energy, and silent chopping technology (stealth chop). F. Color: White. G. Material: Printed circuit board (PCB). H. Dimensions: 6.34 x 4.96 x 1.1 inches. I. Package contents: - 5 TMC2208 v2.0 driver modules; - 5 black heat sinks; - 1 screwdriver (randomly distributed, the style cannot be specified). Only the above package contents are included, and no other products are provided. J. Note: Light reflection and different displays may cause slight differences between the color of the item and the actual object. A measurement error of +/- 1 - 3 cm is acceptable.
