This is a six-pack of TMC2209 V1.3 stepper drivers, the quiet StealthChop-based chip that has become the default upgrade for 3D printer mainboards. Each module handles up to 2.8A peak, supports UART configuration for tuning current and microsteps in firmware, and also runs in plain Step/DIR mode with no UART wiring. The V1.3 revision is the common layout with the heatsink pad on top and a diag pin broken out for sensorless homing. Six units cover a full Octopus or Manta board with spares, and they drop into SKR V1.4 Turbo, SKR 3 and Octopus Pro boards without adapters. Against A4988 or DRV8825 drivers they are far quieter and smoother, though they run hotter and need airflow.

Owners of SKR and Octopus boards report a large drop in motor noise after swapping in TMC2209s, and UART setup works as expected once firmware is configured. Complaints center on heat and on units that arrived dead or with poor solder joints.
This set includes six TMC2209 V1.3 stepper motor drivers in the StepStick format, made for 3D printer control boards. The drivers are rated for 2.8A current and are described as ultra silent in operation.
They can be controlled over UART or run in Step/DIR mode.
