# Adafruit STSPIN220 Stepper Motor Driver Breakout Board

## Overview

![stepper motor spinning with the breakout](https://cdn-learn.adafruit.com/assets/assets/000/138/212/medium800thumb/adafruit_products_6353-05.jpg?1751979131 )

Stepper motors are used for CNC machines, 3D printers, and whenever one needs precise, powerful motion. But to get good behavior from steppers, you need a motor driver chip that can provide high bursts of current. And for smooth motion, it must be able to PWM that current for microstepping support. You can DIY this with a lot of timers, a microcontroller, and an H-Bridge chip - _or_ you could take the easy way out and use an **Adafruit STSPIN220 Stepper Motor Driver Breakout Board** , which makes controlling stepper motors easy-breezy, with a simple GPIO-only interface.

![front view of the board](https://cdn-learn.adafruit.com/assets/assets/000/137/556/medium800/adafruit_products_6353-04.jpg?1749734227 )

All you need is two output pins: no timers, PWM, or a real-time microcontroller. Set the DIRection pin high or low to set the spin orientation. Then, toggle the STEP pin to take one step or microstep at a time. By default the board is configured for 1/16 microsteps per toggle. However, if you want to connect the RESET pin and the two mode pins, you can set anywhere from 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128 or even 1/256! The microstep mode is determined by the DIR/STEP/MS1/MS2 pin states when coming out of reset. The step/microstep mode can be adjusted on the fly! LEDs on the DIR and STEP pins let you get visual feedback of your motor signal.

![back view of the board](https://cdn-learn.adafruit.com/assets/assets/000/137/557/medium800/adafruit_products_6353-02.jpg?1749734283 )

 **We stock quite a few of these "DIR/STEP" stepper drivers - each with its strengths! Here's a quick comparison:**

- [A4988](https://www.adafruit.com/product/6109) - Classic low-cost chip! 8-35V at 2A per coil. Only up to 1/16 microstepping, doesn't 'silent step' so it's noisier.
- **[TMC2209](https://www.adafruit.com/product/6121)** - Super silent 3D printer fav! 5-28V at 2.8A peak per coil. Up to 1/256 microstepping, stallGuard, spreadCycle, but some of the settings & special capabilities require using the UART-interface configuration.
- **[STSPIN220](https://www.adafruit.com/product/6353)** - Great for lower voltages! 1.8-10V at 1.3A per coil. Up to 1/256 microstepping, GPIO-only needed for configuration.

The STSPIN220 is a popular driver chip, especially for smaller/lower-voltage motor driving. Often it comes in "3D printer breakout" designs: those breakouts are great for plugging into motherboards, but are a little tough to use for prototyping. Our version comes with terminal blocks for the motor power and stepper wires, plus nicely labeled pins for control and mounting holes.

![terminal block view of the board](https://cdn-learn.adafruit.com/assets/assets/000/137/558/medium800/adafruit_products_6353-03.jpg?1749734328 )

This driver has built-in current-limiting capability. To use the current limiting capability, twist the onboard potentiometer: when all the way to the right, we can get to up to 2A max. Note that higher currents will heat up both the motor driver and stepper, so you may need to add heatsinking to the chip. We don't include a heatsink, but you can get [a tall ~80ºC/W](https://www.adafruit.com/product/1493) or [short ~90ºC/W heatsink](https://www.adafruit.com/product/1515) to attach on top.

**Features:**

- STSPIN220 microstepping driver with translator and overcurrent protection
- Motor voltage from 1.8 to 10V
- Vdd/Logic voltage from 3V to 5V, use with anything from an Arduino-compatible or ESP32 to Raspberry Pi or other Single Board Computer
- Terminal screw block connections for easy VMotor power and 4-wire bi-polar stepper motor connection with 26-20AWG slots, 2.54mm / 0.1" spacing
- Control steppers using only two pins: DIRection and STEP
- Defaults to 1/16 microstep mode, change by setting DIR/STEP/MS1/MS2 pins and resetting (see [STSPIN220 datasheet](https://www.st.com/en/motor-drivers/stspin220.html) for pin configuration)
- Red and Green LEDs on DIR signal to let you know forward or backward motion
- Yellow LED on STEP to let you know that motor driver is being moved
- Reset and Enable control lines for low power / deactivation
- Potentiometer to set current limiting, up to ~1.3A
- 47uF 16V electrolytic capacitor on motor power
- Four mounting holes

# Adafruit STSPIN220 Stepper Motor Driver Breakout Board

## Pinouts

Warning: The coils are matched as 1A/2A and 1B/2B.

![front and back views of the board](https://cdn-learn.adafruit.com/assets/assets/000/137/571/medium800/adafruit_products_double.jpg?1749738927 )

## Power

- **VDD** - This is the logic voltage input. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V. It can be powered between from 3.3V to 5V.
- **+** (terminal block) - This is the motor voltage input. Supply 1.8-10VDC for your motor.
- **GND** / **-** (terminal block) - common ground for power and logic.

## Current Potentiometer

On the right side of the board is the current potentiometer. This potentiometer limits the current output to the motor. When the potentiometer is all the way to the right, you can get up to about 1.3A max.

## Terminal Block Bipolar Stepper Motor Connections

- **1A** and **2A** - The first set of motor control outputs connected to DMOS bridge 1.
- **1B**  and **2B** - The second set of motor control outputs connected to DMOS bridge 2.

## Stepper Control Pins

- **DIR** - This is the direction control pin. You can set this pin high or low to set the spin orientation. Pulling it high turns the motor clockwise. Pulling it low turns it counterclockwise.
- **STEP** - This is the microstep control pin. Toggle this pin to take one step or microstep at a time. By default, the driver is set to 1/16 microstep mode.

## LEDs

- Green LED - The green LED is tied to the DIR pin. It is labeled **F** on the board silk. It is lit when the motor is being driven counterclockwise when the DIR pin is low.
- Red LED - The red LED is tied to the DIR pin. It is labeled **B** on the board silk. It is lit when the motor is being driven clockwise when the DIR pin is high.
- Yellow LED - The yellow LED is tied to the STEP pin. It is labeled **S** on the board silk. It is lit when the motor driver is being moved.

## STSTEP220 Control Pins

- **EN ** - This is the enable pin. Pull this pin low to disable the output to the motors.
- **RST** - This is the reset pin. Pull this pin low to reset the STSTEP220. This pin is also used when setting the microstep mode.

## Microstep Selection Pins

There are two pins ( **MS1** , **MS2** ) that can be pulled high or low in combination with the **DIR** and **STEP** pins to change the default 1/16 microstep mode where all four pins are open/high. The table below shows the pin combinations to change to the different modes. For example, if you wanted to use 1/4 microstep mode, you would tie **STEP** and **MS1** to ground (closed/low) and leave **DIR** and **MS2** as-is (open/high).

You'll need to reset the breakout with the  **RST** pin to enable a new mode since it is latched at power-up.

![mode jumper table](https://cdn-learn.adafruit.com/assets/assets/000/137/584/medium800/adafruit_products_Screenshot_2025-06-12_111844.jpg?1749741624 )

This table is also available on [page 9 of the STSPIN220 datasheet](https://cdn-learn.adafruit.com/assets/assets/000/137/563/original/stspin220.pdf?1749734919). If you don't want to have to worry about referencing this table for your project, you can use the Arduino or CircuitPython library to set the step or microstep mode instead or doing it manually.

## Python Installation of STSPIN Library

You'll need to install the **Adafruit\_Blinka** library that provides the CircuitPython support in Python. This may also require enabling I2C on your platform and verifying you are running Python 3. [Since each platform is a little different, and Linux changes often, please visit the CircuitPython on Linux guide to get your computer ready](https://learn.adafruit.com/circuitpython-on-raspberrypi-linux)!

Once that's done, from your command line run the following command:

- `pip3 install adafruit-circuitpython-stspin`

If your default Python is version 3 you may need to run 'pip' instead. Just make sure you aren't trying to use CircuitPython on Python 2.x, it isn't supported!

## CircuitPython Usage

To use with CircuitPython, you need to first install the **Adafruit\_CircuitPython\_STSPIN** library into the **lib** folder on your **CIRCUITPY** drive. Then you need to update **code.py** with the example script.

Thankfully, we can do this in one go. In the example below, click the **Download Project Bundle** button below to download the necessary libraries and the **code.py** file in a zip file. Extract the contents of the zip file, and copy the **entire**  **lib**  **folder** and the **code.py** file to your **CIRCUITPY** drive.

Your **CIRCUITPY/lib** folder should contain the following file:

- **adafruit\_stspin.mpy**

![CIRCUITPY drive](https://adafruit.github.io/Adafruit_CircuitPython_Bundle/stspin_stspin_microsteps.py.png )

## Python Usage

Once you have the library `pip3` installed on your computer, copy or download the following example to your computer, and run the following, replacing **code.py** with whatever you named the file:

`python3 code.py`

## Simple Test
https://github.com/adafruit/Adafruit_CircuitPython_STSPIN/blob/main/examples/stspin_simpletest.py

In the simple test, only the direction and step pins are used to rotate the stepper motor clockwise and counter clockwise at the default 1/16 microsteps in the loop. You'll see your stepper motor rotate back and forth with a 1 second pause between each turn.

## Microstep Mode Test
https://github.com/adafruit/Adafruit_CircuitPython_STSPIN/blob/main/examples/stspin_microsteps.py

In the microstep mode test, all of the pins are used to set the different microstep modes on the STSPIN220. In the loop, the different microstep modes are cycled. When a new mode is initiated, the stepper motor makes a full rotation clockwise and then counter clockwise. In the serial console, you'll see output from this process printed out for each microstep mode.
