11 open source boards using the L293D
Real designs built with the L293D, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.

Microcontrollers on boards using the L293D
What boards using the L293D are built for
L293D: common questions
Where can I find a L293D reference design?
Each of the 11 boards on this page is a real design using the L293D. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the L293D use?
Most are built on AVR/Arduino (4) and ESP32 (2).
How big is a typical board using the L293D?
The median is 160 × 110 mm, and 73% are two-layer designs.
What is the most popular open source board using the L293D?
By GitHub stars, Line follower by thebiguno, with 75 stars.
Can I simulate one of these boards using the L293D before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
