Features: 1. Continuing the characteristics of the TMC series driver, the mute effect is good, and the internal 16 of the chip is expanded by 256 subdivisions. 2. The drive current is larger, the maximum peak current can reach 2.5A, and the stable printing current can reach 1.8A. 3. Compared with other TMC series drivers, the heating efficiency is lower and the cooling effect is better. 4. Support UART e, perfect use with MKS SGEN-L, no jumper is needed product description MKS TMC2209 has all the functions of TMC2208 and can completely replace TMC2208. At the same time, the heat is smaller, it can support higher current, and infinite zero return.
