Motors and servos

Choose by actuator type first: brushed DC motor, stepper motor, RC servo, solenoid or Raspberry Pi HAT. Similar-looking motor boards are rarely drop-in substitutes.

Arduino DC motor shields

Arduino shield pins + PWM → brushed DC motors

Shield-format boards are convenient when the project is already Arduino-shaped. They still lock in motor voltage, channel count, pin use, current limit and stack height.

from $10.901 boardIn stock

Legacy and small brushed-DC H-bridges

PWM + direction → brushed DC motors or solenoids

Use these for simple bidirectional brushed-DC loads when current, heat and voltage are inside the board limits. They are not stepper carriers or RC-servo controllers.

Modern dual DC motor drivers

PWM / direction / mode pins → two DC motor channels

TB6612FNG and DRV8833-style boards suit many small robots, but ratings, pinout, braking modes, standby behavior, headers and current limiting vary by board.

Can I swap these?

Pick the board you have - we'll show what we know about swapping it.

Known swap options (1)

General board checks (6)

Name the load first: brushed DC motor, bipolar stepper, RC servo, solenoid or motor HAT.
Match motor/load supply voltage, continuous current, peak or stall current, cooling and wire/connector rating.
Confirm the control method: PWM/direction, step/direction, I2C/Qwiic, servo pulse or board-specific library.
Check pinout, enable/standby pins, braking/stop behavior, current-limit setup and any required flyback/protection.
Do not power motors or servos from a microcontroller regulator or Raspberry Pi 5 V rail unless the board source explicitly supports it.
Use the linked vendor page or datasheet as the final authority for ratings and wiring.

Arduino DC motor shields

2x1A DC Motor Shield for Arduino

Arduino-format L293 shield for two 7-12 V brushed DC motors at up to 1 A per channel. It stacks onto Arduino boards and uses PWM speed control, so it is a shield-level design choice rather than a bare driver swap.

$10.90

Legacy and small brushed-DC H-bridges

Full-Bridge Motor Driver Dual - L298N

Dual full-bridge driver module built around the ST L298N. Drives two brushed DC motors or one bipolar stepper from a separate motor supply, with PWM and direction control per channel.

$4.95

L9110H H-Bridge Motor Driver for DC Motors - 8 DIP

Small 8-DIP H-bridge chip for two solenoids or one bidirectional DC motor. Not a stepper carrier, Qwiic board or RC-servo controller.

$1.50

Modern dual DC motor drivers

SparkFun Motor Driver - Dual TB6612FNG (1A)

TB6612FNG dual DC motor driver board. Compare continuous current, braking/stop modes, standby behavior, supply voltage and pinout before swapping with L298N, DRV8833 or another TB6612 breakout.

$14.77

SparkFun Motor Driver - Dual TB6612FNG (with Headers)

SparkFun TB6612FNG dual DC motor driver with pre-soldered headers. Functionally close to the headerless TB6612FNG board, but connector format and board wiring still matter.

$14.50

Fermion: TB6612FNG 2x1.2A DC Motor Driver (Breakout)

Compact TB6612FNG dual DC motor driver breakout. It can feel like an L298N upgrade path, but voltage, current, pin mapping and code assumptions still need review.

$4.50

Adafruit DRV8833 DC/Stepper Motor Driver Breakout Board

Dual H-bridge breakout for two DC motors or one bipolar/unipolar stepper. Useful low-voltage alternative to TB6612-class boards, but motor voltage, current limit and pinout still need checking.

$5.95

High-current single DC drivers

15A Single DC Motor Driver

High-current single brushed-DC motor driver for larger loads. Treat the 36 V / 15 A class, protection features, wiring, cooling and supply sizing as the whole design problem, not a simple pin-compatible replacement.

$18.90

Stepper driver carriers and modules

Pololu A4988 Stepper Motor Driver Carrier, Black Edition

Pololu A4988 carrier for a single bipolar stepper motor with step/direction control, microstepping and adjustable current limiting.

£16.50

EasyDriver - Stepper Motor Driver

Stepper driver board for pulse-controlled stepper projects. Use where a step/direction style stepper driver is expected, not as a DC motor or servo substitute.

$18.50

SparkFun ProDriver - Stepper Motor Driver (TC78H670FTG)

SparkFun stepper driver board built around the Toshiba TC78H670FTG bipolar stepper driver IC. Compare stepper current, setup, wiring and library examples before substituting for A4988, EasyDriver or TB6600 boards.

$22.95

TB6600 Stepper Motor Driver (High-Precision 32 Micro-step, 4A)

Two-phase stepper driver module with microstep and current adjustments. Use for stepper motors with a suitable supply and cooling, not for RC servos or plain brushed DC loads.

$20.00

Small 5 V stepper motor assemblies

28BYJ-48 Stepper Motor Module with Driver for STEM Robotics (5V, 0.9 kgf·cm)

All-in-one 5 V 28BYJ-48 geared stepper module with integrated driver. It is a complete small stepper assembly, not just a driver carrier for arbitrary bipolar steppers.

$9.90

Step Motor 5V

Small 5 V 28BYJ-48 stepper motor. Pair it with a suitable driver and do not treat it as interchangeable with a DC motor or RC servo.

$7.95

Controller-mediated motor driver

SparkFun Qwiic Motor Driver

Qwiic motor driver. It changes the project to an I2C/Qwiic control path rather than raw PWM/direction pins, so firmware and wiring are part of the substitution decision.

$23.78

Raspberry Pi motor and servo HATs

Raspberry Pi Motor & Servo Addons/HATs | Kiwi Electronics

Vendor motor and servo HATs category page. Use it as a starting point; pick a specific HAT and its onboard driver chip before designing around it.

DC Motor Driver HAT(V1.0) for Raspberry Pi

Raspberry Pi DC motor driver HAT for two DC motors, including encoder-capable motors, using I2C communication with an onboard STM32 and TB6612FNG driver chip.

$14.90

SparkFun Servo pHAT for Raspberry Pi

Raspberry Pi Servo pHAT for controlling up to 16 servo motors over I2C. It belongs with servo-controller boards, not DC motor H-bridges or bare RC servos.

$13.95

RC servos

9g 180° Micro Servo (1.6kg)

Complete 9 g 180° RC micro servo, not a motor driver board. Match voltage, torque, travel angle, connector, mechanical size and stall-current headroom.

$3.50

Digital Servo (DS-929MG)

Digital RC servo with metal gearing. Match servo voltage, torque, travel, spline/horn, size, connector and stall-current headroom rather than comparing it to motor-driver boards.
