Motor Control is one of the fundamentals of robotics. In many projects, you would have to either control motor speed or its direction with a particular form of circuitry. Two approaches can be followed, either you can make your motor controller (an H-Bridge) or buy an off-the-shelf solution. Buying an IC or a module that takes care of the motor control removes a lot of physical hassle and, therefore, we have covered some of the best motor drivers you can purchase right now online. For people interested in a motor driver that works with your Raspberry Pi board, these are the 10 best motor drivers available in the market right now.
10. ULN2003 Motor Driver by Beautiful Store Shop(10.99$)
This board allows you to control servo, DC and stepper motors. The simple circuit board connects quickly to a Raspberry Pi, but it is not that durable.
9. Makerfire® Raspberry Pi L298N Motor Driver Board(132$)
The motor driver utilizes STL298N ZIP chip and works on 5V. You can drive a maximum of a 12V motor with this, and it is fitted with 3.5mm terminals for easy connectivity.
8. Raspberry Pi Motor Driver Board V1.0(72.97$)
The operating voltage for the motor connected to this module is between 6V~28V DC. The maximum amount of current that a motor can draw from this module is 2A. It also has current limit threshold detection.
7. IRF520 Button MOSFET Driver Module(5.98$)
MOSFET modules are much quicker than simple TTL logic as they have much higher switching frequency. The module works at 3.3V. Hence, it is low power as compared to some.
6. Adafruit DC & Stepper Motor HAT for Raspberry Pi(27.49$)
The module has four bridges of maximum 1.2A per bridge. You can run 4 DC motors on 4.5VDC to 13.5VDC with this module, and it works with Raspberry Pi Model A+, B+, or Pi 2.
5. Raspberry Pi Motor Controller Pi-Plate(33.99$)
Like some of the best modules, this one also allows you to control 4 DC motors or 2 stepper motors at once. You can use a 16Bit accuracy to control the speed of the motor while the complete board weighs only 3 ounces.
4. CJRSLRB® L298N Motor Drive Controller(6.99$)
This module uses 78M05 IC and works between 5V to 12V power supply. The device uses a large filter capacitor and has diodes to protect any damage from reverse current. The device is immune to over heating even though it can work at a maximum of 25W.
3. SMAKN® 16 Channel PWM/Servo Driver IIC interface-PCA9685 (13.60$)
PCA 9685 chip conserves power yet provides good switch speed. In groups of 4, you can connect up to 16 servos at once making this one of the most versatile boards on our list.
2. L298N Dual H Bridge DC Stepper Motor Drive Controller Board(9.50$)
The bridge can sustain a combined power of over 70W and what’s remarkable about this bridge is that it can drive motors on as high as 35V with a maximum of 2A current.
1. DROK® L298N Motor Drive Controller Board (6.99$)
Drok board is the most popular of all the motor driver boards. The product has over 102 customer reviews and an average consumer rating of 4.5/5 stars. The board requires 5V logic while it can run up to 15V drive voltage. The board is fitted with all the protective circuitry such as afterflow diodes and a large capacity filter capacitance.
