TMC2209 silent stepper driver (StepStick) 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	Pin order varies between boards: match by the printed label. Enable, active LOW. Connect to GND to keep it on
MS1	Non collegato all’ESP32	—	Microstep select. With UART: address bit 0
MS2	Non collegato all’ESP32	—	Microstep select. With UART: address bit 1
UART	Non collegato all’ESP32	—	Single-wire UART (optional, via a 1 kΩ resistor for TX)
PDN	Non collegato all’ESP32	—	Power down / UART. Leave unconnected for STEP/DIR use
CLK	Non collegato all’ESP32	—	Clock input. Connect to GND (internal clock)
STEP	Ingresso (lo pilota l’ESP32)	D26	One pulse = one (micro)step
DIR	Ingresso (lo pilota l’ESP32)	D27	Direction
VM	Non collegato all’ESP32	—	Motor supply 5.5 to 28 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
VIO	Alimentazione	3V3	Logic supply: 3V3
GND	Massa	GND
DIAG	Uscita (la pilota il componente)	D32	Stall / error output (StallGuard). Optional
INDEX	Uscita (la pilota il componente)	D33	Index pulse output. Optional

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.
