Summary of Homemade Dual H-Bridge – L298 Breakout Board using Arduino
This article details the creation of a homemade Dual H-Bridge motor driver using the L298N IC, suitable for controlling DC and stepper motors. The project involves assembling components on a perfboard following a schematic, with steps including preparation of the board, component placement, and soldering. Supplementary files and schematics for design refinement are provided. The build emphasizes modular soldering per component type and supports Arduino integration.
Parts used in the Homemade Dual H-Bridge using the IC L298N:
- Perfboard 13x26 holes (3.5 x 7.0 cm)
- 2 x AK300/3 connector
- 1 x 8-pin female header connector for Arduino
- L298N IC (Multiwatt15 package)
- 8 x 1N4001 diodes
- 2 x 100nF capacitors
- 2 x 0.47 Ohm 1W resistors
- Wires (green and blue colors)
This is my homemade Dual H-Bridge using the IC L298N.
For control DC motors or step Motors ao other purposes just like you need.

Step 1: Hardware and Materials
COMPONENTS:
1 x perf board 13×26 holes (3,5 x 7,0 cm)
2 x AK300/3 connector
1 x 8 Header female connector for Arduino
1 x L298N (Multiwatt15)
8 x 1N4001 Diode
2 x 100nF capacitor
2 x 0,47Ohm x 1W Resistor

Step 3: 1st Step – Perfboard, holes location
Make a Board with 3,5 x 7,0 cm or 13 x 26 holes.
Locate in this board, all holes that we will use for the components.
Step 4: 2nd Step – Components
After sanding and cleaning the board, put all components in it according of the diagram above and schematic.
For this, bend components properly.
Do the soldering for each group of components independently, for example:
diodes first and then connectors and then capacitors and resistors and finally the L298N IC; or in what order you want or you are used to do.
