Dual L298HN Motor Driver

June 25, 2011 BuildIts Electronics

I built this motor controller to power the motors for an Arduino-controlled robot I am working on. It uses 2 L298HN dual full-bridge chips, each of which is capable of powering 2 DC motors at 2A each, with bidirectional control. You can get up to 3 of the L298HN chips for free from the ST website. The rest of the parts needed are as follows:

2.5" x 3.125" perfboard
4 2-Position PC Mount Terminal Strips
5 3-Position PC Mount Terminal Strips
22 AWG Solid Core Hookup Wire
2 Heatsinks for the L298's

Components:

Placement:

Soldered:

I cut an old northbridge heatsink in half and drilled and tapped it to fit the chips:

Here's the board's layout:

Next to an Arduino for a size reference:
