LED Cloud: common questions

What microcontroller does the LED Cloud use?

The LED Cloud is built around the ESP32-WROOM-32D (16MB), from the ESP32 family.

How big is the LED Cloud PCB?

The LED Cloud measures 171 × 124 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the LED Cloud?

377 components, from 20 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 LED Cloud design files?

From the wasauce/AirCloudPCBs repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the LED Cloud design in my own project?

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

Can I test firmware for the LED Cloud 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.
