Dual H-Bridge – Arduino L298 Breakout Board




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

Breakout Board

This is the basic schematic. It works perfectly.

A more advanced schematic and board for eagle cad, you can download from the link below.

1st Step – Perfboard, holes location

schematic Breakout Board

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.

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.

Soldering and wired Tracks

Following the schematic and diagram above, first of all make all soldered tracks in the bottom layer of the board.
After that, solder the jumper wires making the wired tracks.

Note.
Green wires are on the top layer and blue wires are on the bottom layer of the board.

Major Components in Project

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
Wire (green and blue colors)
