From the project

Devkit for LED strips, with wide range of voltage inputs, and options for current limited outputs

Hardware design files for the Lux et Tenebris Devkit - an ESP32-based LED controller development board with integrated OLED display, WS2812B LED channels, and multiple output configurations.

The Lux et Tenebris hardware consists of custom PCB designs created in KiCad, providing a compact platform for controlling addressable LEDs, RGB strips, and other lighting applications. The board integrates power management and some I/O expansion ports.

Marajoara V2: common questions

What microcontroller does the Marajoara V2 use?

The Marajoara V2 is built around the ESP32-C3-Supermini, from the ESP32 family.

How big is the Marajoara V2 PCB?

The Marajoara V2 measures 239.7 × 192.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Marajoara V2?

90 components, from 22 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 Marajoara V2 design files?

From the machadoleonardo94/lux-et-tenebris 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 Marajoara V2 design in my own project?

The repository has no license, so all rights stay with machadoleonardo94. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Marajoara V2 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.
