About this item

The BIGTREETECH BTT EZ2209 V1.0 is a refined iteration of the TMC2209 stepper motor driver, engineered specifically for simplifies integration with 3D printers using BIGTREETECH’s EZ‑series motherboards. Encased in a pin‑less, anti‑misplugging 2‑in‑1 form factor, this driver merges the high-performance TMC2209 chip with a sizable aluminium heat sink to deliver efficient thermal management and user-friendly installation—no pokey pins and minimal risk of improper insertion. With support for both StealthChop2 (near‑silent operation) and SpreadCycle (high-dynamic motor control), it enables smooth motion across a wide speed range, while StallGuard4 offers sensorless detection of stalled motors. The chip’s CoolStep™ technology dynamically modulates current for up to 75% energy savings. Available in both Step/Dir and UART modes, it offers flexible communication for firmware tuning and advanced diagnostics. Compact (just ~18.5 × 19.8 mm), it fits neatly into EK‑design slots or works with EZ‑driver connectors on legacy boards. Backed by robust construction (4‑layer PCB) and compatibility with Manta E3 EZ, SKR 3 EZ, I3 Mega, Octopus V1.2, and more, the EZ2209 V1.0 delivers reliable, quiet, and precise control ideal for modern 3D printing needs.
