DRV8825 stepper driver con ESP32

Alimentazione 3.3-5 V Bus GPIO

Pin e collegamento all’ESP32

Pin	Ruolo	Pin ESP32	Note
EN	Ingresso (lo pilota l’ESP32)	D25	Enable, active LOW. Leave unconnected to keep it on
M0	Non collegato all’ESP32	—	Microstep select
M1	Non collegato all’ESP32	—	Microstep select
M2	Non collegato all’ESP32	—	Microstep select
RST	Ingresso (lo pilota l’ESP32)	D26	Must be HIGH: tie RST and SLP to 3V3
SLP	Ingresso (lo pilota l’ESP32)	D27	Must be HIGH: tie RST and SLP to 3V3
STEP	Ingresso (lo pilota l’ESP32)	D32	One pulse = one step
DIR	Ingresso (lo pilota l’ESP32)	D33	Direction
VMOT	Non collegato all’ESP32	—	Motor supply 8.2 to 45 V from a separate supply. Add a 100 µF capacitor
GND_MOT	Massa	GND	Motor supply ground
B2	Non collegato all’ESP32	—	Motor coil B
B1	Non collegato all’ESP32	—	Motor coil B
A1	Non collegato all’ESP32	—	Motor coil A
A2	Non collegato all’ESP32	—	Motor coil A
FAULT	Uscita (la pilota il componente)	D23	LOW on over-current or over-temperature
GND_LOGIC	Massa	GND	Logic ground: to the ESP32 GND

Collegamento consigliato per l’ESP32 DevKit a 30 pin, evitando i pin della flash, di sola lettura e di strapping. BoardPilot lo controlla mentre colleghi.
