DC Gear Motor with L298N Driver
Classic brushed DC motor + dual H-bridge driver combo.
A geared DC motor paired with the ubiquitous L298N dual H-bridge driver — the standard starting point for wheeled robots.
Specifications
| Motor | Brushed DC gear motor — the common yellow "TT motor" spec is ~200 RPM at 6V, ~1:48 gear ratio |
| Driver | L298N dual H-bridge, 2A per channel |
| Control | One direction pair (IN1/IN2) plus one PWM speed pin (ENA) per motor |
| Supply | Motor voltage 5V-35V DC on the driver's VMS terminal, separate from the MCU's own power |
Pinout
| Pin | Name | Description |
|---|---|---|
| 1 | OUT1 / OUT2 | Motor leads — connect directly to the L298N's motor A output terminal, polarity sets default spin direction |
| 2 | ENA | PWM input on the driver — controls motor speed |
| 3 | IN1 / IN2 | Direction inputs on the driver — set which way current flows through the motor |
| 4 | 12V / GND | Motor supply voltage and ground, into the driver's VMS/GND terminal |
This entry covers the motor + L298N pairing as a unit — see the L298N Driver page for the full breakdown of every driver pin if you're wiring more than one motor.
Variants
The TT motor + L298N combo is the standard, well-documented starting point for two-wheel-drive robots. If you already have a driver and just need a motor, or vice versa, buy them separately — the L298N Driver listing covers the module alone. For battery-powered builds where efficiency and heat matter, a TB6612FNG-based driver wastes noticeably less power than the L298N's older BJT H-bridge design.
| Variant | Price |
|---|---|
| TT Gear Motor + L298N | ~$3-5 (motor) + ~$2-4 (driver) |
| L298N driver alone | ~$2-4 |
| N20 micro gear motor + TB6612FNG | ~$4-8 (motor) + ~$3-5 (driver) |
