Bigtree Tech TMC2209 UART V1.3 Stepper Motor Driver for 3D Printer

The BIGTREETECH TMC2209 V1.3 is a sophisticated stepper motor driver IC designed for two-phase stepper motors. It's known for its ultra-quiet operation thanks to StealthChop2 technology, making it a great upgrade for noisy 3D printers. It supports both UART and STEP/DIR control modes, giving users flexibility in how they interface with the driver. A key feature is its sensor less homing capability using StallGuard4, which eliminates the need for physical limit switches. It's widely compatible with various 3D printer motherboards, making it a versatile and cost-effective upgrade option.
