Adafruit Motor/Stepper/Servo Shield for Arduino v3 Kit
The original Adafruit Motorshield kit is one of our most beloved, so we decided to make something even better. We have upgraded the shield kit to make the bestest, easiest way to drive DC and Stepper motors.
Pinout
- SDA
I2C data line used by the shield PWM/motor controller; Adafruit states only SDA and SCL plus 5V and GND are required to drive the motors.
Type · signal - SCL
I2C clock line used by the shield PWM/motor controller; Adafruit states only SDA and SCL plus 5V and GND are required to drive the motors.
Type · signal - 5V
Arduino 5 V logic rail required with SDA/SCL/GND for shield control.
Type · powerVoltage · 5V logic rail, source states 5v is required with SDA/SCL/GND. - GND
Common ground required with SDA/SCL and 5 V for shield control.
Type · groundVoltage · 0V reference - M1
DC motor / stepper motor output port M1; Adafruit library docs select motor ports M1, M2, M3 or M4.
Type · motor outputVoltage · Motor supply, source FAQ states 5-12VDC power via POWER terminal blocks or Arduino DC barrel/VIN jumper.
Start wiring
I2C · 5V logic rail, source states 5v is required with SDA/SCL/GND. · 0V reference
Confirm the data interface matches your host board.
Module pins: 5V, GND, SDA, SCL. Schematik maps them to your board in the app.
