Le circuit imprimé, rendu depuis les fichiers de ce dépôt. Fond transparent : lisible en thème clair comme en thème sombre.

Les afficheurs « holographiques » DIY qu'on trouve en ligne se ressemblent tous : un ESP32, un petit écran OLED monochrome et une breadboard. Le résultat est saccadé, minuscule, et l'électronique est visible. Ce projet répond à la même envie mais en produit final : image couleur fluide, électronique intégrée sur une carte sur mesure, et surtout une…

Cube hologram: common questions

What microcontroller does the Cube hologram use?

The Cube hologram is built around the ESP32-S3-WROOM-1U-N16R8, from the ESP32 family.

How big is the Cube hologram PCB?

The Cube hologram measures 48 × 52 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Cube hologram?

55 components, from 30 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 Cube hologram design files?

From the Honzaaa45/cube-hologram-pcb 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 Cube hologram design in my own project?

Yes, under the terms of its MIT license, which Honzaaa45 chose for the repository.

Can I test firmware for the Cube hologram 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.
