BTT TMC2209 v1.2 Stepper Driver
Couldn't load pickup availability
BIGTREETECH TMC2209 v1.2 is a quiet StepStick-format driver for two-phase 3D-printer stepper motors. Use it for standard plug-in driver sockets when you want UART control, STEP/DIR compatibility, StealthChop2 quiet motion, and up to 2.0A RMS / 2.8A peak drive current.
Why this over a basic stepper driver?
- Quieter motion: the TMC2209 platform supports StealthChop2 for low-noise movement and SpreadCycle for higher dynamic load.
- UART or STEP/DIR: works in standard STEP/DIR setups and can be configured over UART on compatible controller boards.
- Sensorless homing support: StallGuard4 can report motor load/stall conditions when the firmware and board wiring support it.
- CoolStep current control: dynamic current regulation can reduce heat and power draw in supported configurations.

Fitment and alternatives
- Use this for standard StepStick-style sockets on compatible 3D-printer controller boards.
- If your BTT board uses EZ-driver sockets, use the BTT EZ2209 Stepper Motor Driver instead.
- If you are choosing newer driver features rather than a drop-in TMC2209 replacement, compare against the BTT TMC2240 Stepper Motor Driver.
Installation notes
- Do not hot-plug stepper drivers. Power the controller off before installing or removing the module.
- Confirm socket orientation before insertion; reversed installation can damage the driver or control board.
- Add airflow or heatsinking appropriate to your run current and enclosure temperature.
- This is not an EZ-format or SPI-format driver module.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
