What the AI looks for in 3D Printer Interface & Driver Modules

Driver chip: TMC2209 gives quiet StealthChop, sensorless homing and UART control. A4988 and DRV8825 are louder and more basic. The driver chip sets noise, current headroom and which firmware features you can use.
UART vs standalone mode: Your board and the driver's jumper or pin configuration must support UART if you want software current control. In standalone mode you set current with a potentiometer, and sensorless homing is unavailable.
Current capacity: Driver RMS rating must exceed your motor run current, with cooling. Overloaded drivers overheat and skip steps.
Display compatibility: Confirm the screen's protocol and cable type, such as EXP1/EXP2 for 12864 screens or serial for touchscreens, against your board and firmware. Many screens only work with specific boards or firmware builds.
Format: Use StepStick pin layout for socketed boards. Some boards need their own proprietary driver modules. A mismatched form factor will not seat in the socket.

Inserting a driver rotated in its socket, which can destroy both driver and board.
Running drivers without heatsinks or airflow.
Mixing driver chip types on one board without matching firmware settings.

They nearly silence the motors in StealthChop mode, but fans and the power supply stay audible.
