2 open source boards using the HV-LV
Real designs built with the HV-LV, 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 HV-LV
What boards using the HV-LV are built for
HV-LV: common questions
Where can I find a HV-LV reference design?
Each of the 2 boards on this page is a real design using the HV-LV. 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 HV-LV use?
Most are built on ESP32 (2).
How big is a typical board using the HV-LV?
The median is 172 × 152 mm, and 50% are two-layer designs.
What is the most popular open source board using the HV-LV?
By GitHub stars, Unicorn by danwerner21, with 50 stars.
Can I simulate one of these boards using the HV-LV 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.
