README
README.mdRay module
The ray module is a 3-channel LED controller, designed to be small, and built on the OHAUT framework.
OHAUT framework provides the common web interface, WiFi management, connectivity to other smart devices (like Alexa , homeassistant, etc..), as well as an update system which allows firmware to be published on this repository (see the gh-pages branch ), long term it probably makes more sense to release via github releases of binaries.
The firmware code for this device is available in the firmware directory.
The hardware design for this devices is available in the hardware directory.

Questions
How big is the Ledboard PCB?
It measures 60 × 49 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ledboard use?
57 parts, built around the ESP-12E, FAN3100TSX, LM1117-3.3 and IRF540N. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Ledboard KiCad files?
From the ohaut/ray repository on GitHub, at the commit this page was made from: the board is hardware/base_prototype/pcb/ledboard.kicad_pcb and its schematic hardware/ray2/ray2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ledboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask ohaut before reusing the design.
