A compact TMC2208 module for quiet bipolar stepper control in 3D printers, CNC machines and motion projects. It supports conventional STEP/DIR control or UART configuration, works with 3.3 V or 5 V logic, and includes a blue aluminium heatsink for the reverse-side thermal area.

Wiring & getting started
- Switch off every supply
Disconnect motor power, logic power and USB before inserting or wiring the module.
- Match every pin label
Confirm VM, GND, VIO, DIR, STEP and EN against the carrier board. Do not rely on the board outline alone.
- Connect the motor phases
Connect one winding to M1A and M1B, and the other winding to M2A and M2B.
- Fit the heatsink correctly
Remove the protective film and place the flat adhesive base on the large gold thermal area on the reverse of the board.
- Choose the control mode
Set the carrier-board jumpers and firmware for standalone STEP/DIR or UART operation.
- Start conservatively
Begin at a low current setting, make a short slow move, then check motor direction and driver temperature.
Note: Never connect or disconnect motor windings while VM is powered. The module supplier states a 1.4 A maximum and recommends no more than 1.2 A with suitable cooling. Actual current capability depends on heatsink contact, airflow and the assembled machine.
