README
README.mdDMX Controller
DMX controller board based on ESP32 NodeMCU. Implementing both plain DMX and RDM while being able to read the entire DMX frame.
Why?
We have an Theathre stage at school, we do a musical around christmas every year. We wanted to engineer boxes with LED Strips, alarms, etc. These things needed to respond with the lighting we already use, so DMX was chosen. Thus I started working on the controllers to control non traditional lights on the stage.
How?
Now to use the project it's actually pretty simple, you plug in atleast one XLR cable for DMX in the ports, next you wire something up or just use the ESP32 to control DMX. The possibilities are endless, we engineered it in a way that using a Mesh you can connect more things through one Controller.
You need the PCB itself, female headers for the ESP32 and the ESP32 itself. Wire up what you need through the GPIO pins.

Questions
How big is the DMX Controller PCB?
It measures 100 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DMX Controller use?
22 parts, built around the MAX485EAS, XL1509-5.0E1, HB-PH3-25417PB2GOP and 0805W8F1200. 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 DMX Controller KiCad files?
From the koen1711/DMX-Controller repository on GitHub, at the commit this page was made from: the board is hardware/DMX-Controller.kicad_pcb and its schematic hardware/DMX-Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DMX Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask koen1711 before reusing the design.
