The KiCad project lives in the lnvke/DH-LRC-0 repository on GitHub; these links point at the commit this page was built from.

DH-LRC-0: common questions

What microcontroller does the DH-LRC-0 use?

The DH-LRC-0 is built around the ESP32-C6-MINI-1, from the ESP32 family.

How big is the DH-LRC-0 PCB?

The DH-LRC-0 measures 46 × 40 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the DH-LRC-0?

55 components, from 36 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the DH-LRC-0 design files?

From the lnvke/DH-LRC-0 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the DH-LRC-0 design in my own project?

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

Can I test firmware for the DH-LRC-0 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
