Motor drivers

Match the driver to motor current and control style first. A 1.5A H-bridge breakout, a 43A BTS7960 and an I2C PWM expander solve very different problems, even under the same label.

H-bridge breakouts from 1A to 43A (DRV8871, TB6612FNG, BTS7960), stepper drivers (A4988, TMC260, TB6600), I2C servo/solenoid controllers, and Pi/Arduino shields — sized by current and protocol.

DRV8871 (3.6A), Gravity TB6612FNG (2x1.2A) and Fermion HR8833 (2x1.5A) cover small brushed motors; L298N boards like the MDV 2x2A are older, lossier H-bridges that drop more voltage.
For high current, the BTS7960 dual driver handles 43A, Cytron's MD13S 13A, and Dimension Engineering's Sabertooth (dual 5A/12A) and SyRen (10–50A) add regenerative drive plus serial and RC control modes.
The PCA9685 16-channel 12-bit PWM driver is I2C servo control, not an H-bridge — it can't reverse a motor. Adafruit's I2C 8-channel solenoid driver is the same idea for inductive loads.
Raspberry Pi gets dedicated boards — Pololu's DRV8835 dual driver kit, the Dual G2 high-power driver, ThunderBorg and PicoBorg — while Arduino keeps the Motor Shield R3 and the Romeo all-in-one.

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.

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.

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.
