7 open source boards using the EL814
Real designs built with the EL814, 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 EL814
EL814: common questions
Where can I find a EL814 reference design?
Each of the 7 boards on this page is a real design using the EL814. 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 EL814 use?
Most are built on AVR/Arduino (5).
How big is a typical board using the EL814?
The median is 54 × 74 mm, and 100% are two-layer designs.
What is the most popular open source board using the EL814?
By GitHub stars, RelayTrackerController by bask185, with 3 stars.
Can I simulate one of these boards using the EL814 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.
