The DRV8825 Stepper Motor Driver (Header Pins Soldered) is a breakout board for DRV8825 microstepping bipolar stepper motor driver. It operates from 8.2V to 45V and can deliver up to approximately 1.5A per phase. It comes with 0.1"-pitch male header pins installed.
becuase it has 3.3V logic i could control it from Raspberry Pi 5. Using a few GPIOs. Took me a bit to figure out you basically have to set SLP, RST high to make it work. So on the RPI5 i used GPIO 21 to pin 8, GPIO 20, to pin 7, 3.3V reference to pin 6,5,4,3, and 2 (enabled microstepping). GPIO 16 to pin 1, Ground to pin 9 (GND logic), the four motor pin 11,12, 13, 14 connections to the motor, and the + power to to pin 16 and -power to pin 15. You have to use a screwdriver coupled to your voltmeter and GND on the voltmeter to -power on your power supply. Then you can set the reference voltage - if you dont it wont work. For me for a NEMA17 the reference voltage was 0.84 V. The reference voltage could only be set if was all connected.

Bon pilote pas à pas
Fonctionne bien. Bon contrôle du courant entraînant un stepper de 1,3 A à 2,8 V à 1 A avec un entraînement de 12 V. Utilisez EN 'pin plutôt que SLP' pour libérer le moteur, le mode veille prend plus de temps à se réveiller.

Good stepper driver
Works well. Good current control driving 1.3A 2.8v stepper at 1A with 12v drive. Use EN' pin rather than SLP' to release motor, sleep mode takes longer to wake from.
