Hvac: common questions

What microcontroller does the Hvac use?

The Hvac is built around the nRF54L10-QDAA, from the Nordic nRF family.

How many components are on the Hvac?

57 components, from 57 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hvac design files?

From the amannm/hvac repository on GitHub, which has the schematic and a netlist; the links under Design files point to each one.

Can I use the Hvac design in my own project?

The repository has no license, so all rights stay with amannm. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Hvac without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
