Modifications

Concernant le moteur 2.8V 1.7Amp mentionné, vous pourriez le piloter avec une alimentation 9V (confirmé par Pololu) avec un DRV8825 en limitant activement le courant à 1.5Amp (le maximum toléré par le DRV8825 sans refroissement).

To achieve high step rates, the motor supply is typically much higher than would be permissible without active current limiting. For instance, a typical stepper motor might have a maximum current rating of 1 A with a 5Ω coil resistance, which would indicate a maximum motor supply of 5 V. Using such a motor with 12 V would allow higher step rates, but the current must actively be limited to under 1 A to prevent damage to the motor.
