Overview

WIFI Module is an open-source printed circuit board by NEOgHacking, from the NEOgHacking/DMXion_4Port_Node repository on GitHub, published under the GPL-3.0 licence. It is a 4-layer board of 23 × 13 mm with 18 parts on 22 nets, routed with 129 tracks and 55 vias.

It is built around the ESP8684 and Q22FA12800230. Its parts include 10 capacitors, 2 connectors, 1 resistor, 1 IC and 1 inductor. It belongs with the radio and wireless boards of this library.

DMXion_4Port_Node

DMXion_4Port_Node is a DMX network node based on the official grandMA3 onPC 4Port Node 4k. My version also has 4DMX outputs with RDM support, a EtherCON connector for sturdy Ethernet connections and a display with a rotating knob for configuration. It also uses the Neutrik halo connectors with adressable rgb leds to show the status of the connection. But it also has some differences. First it unfortunately doesn't unlock any parameters in the GrandMA onPC software, but its 20x cheaper. About $100 instead of $2000.

Features

This specific DMX node has some really usefull features.

  1. 4DMX outputs with RDM support.
  2. Neutrik EtherCON connector for a sturdy and lasting connection. Also support for ARTNET and sACN
  3. Color display with a rotary encoder for configuration straigt from the unit itself.
  4. UPS (uniteruptable power supply) For when the power cuts out but you still need it or just for battery operation.
  5. Wifi card slot for wireless operation with the battery.
  6. Powered by a rp2350 for its PIO modules so DMX is correctly implemented and not via a hacked uart or bitbanging a pin.
  7. PoE (Power over Ethernet) For easy setup and as little wires as possible.
  8. USB-C port for power and data to program the rp2350 or configure it.
  9. Cheap PCB. The PCB is 100x72mm 4 layer so its cost is low only $7.

Motivation

I started on making this DMX network node for a few reasons. First i was using a raspberry pi with a usb DMX dongle, this worked but was hard to set up and only got me 1 DMX universe without RDM. It also wasn't the cheapest setup. I wanted it to be cheaper and have more functionallity. Second I once had the opurtunity to use a grandMA3 onPC 4Port Node 4k at school once and realized how usefull it would be. Then my dumb brain said the same sentence it always says: "I can build that myself for cheaper right?" Next thing you know you are 100 hours deep into the project.

Design

The design process was a heck of a ride, at first i started with the simple DMX part but then got to the ethernet. I really wanted PoE so started with the ride. It was a heck of a long ride, i think it took up 1/3 of the projects time its really complex. Also the most complex schematic from the whole project. The rest went pretty smooth. I had recently done another big project my 3D Printer mainboard and learned allot from that! So the rest was pretty straight forward, always some small chip changes here and there but apart from that it went well. The case design also went quick didn't have to high of standards for that but still wanted it to look good. After a whole day that was done. I used KiCad for PCB design, Onshape for 3D design and VScode for Firmware.

Use

To use this product first get the firmware uploaded via the arduino IDE or PlatformIO Then just plug it into a ethernet setup and plug in your DMX devices. Thats it! Its that simple! For config use the display with the rotating knob to select universes, ethernet settings, ext.

Schematic

This is a very long schematic. You can find the whole schematics in .PDF format in the individual PCB design folders. But here are some important ones. First the main schematic of the main PCB. Main schematic Then the schematic of the display module. Display module schematic And finally the esp wifi module. WIFI module schematic

PCB's

So this project has 3 PCB's, first the main PCB that does all the hard work, then a display PCB with a rotary encoder and support components for a bare LCD and finally a custom made WIFI module PCB based on the esp. Main PCB Display_module PCB WIFI_module PCB (there is a glitch in this game, every project i do i get exactly 3 PCB's)

Case

For this project there needed to be a case to protect the PCB from the outside world. I did this in onshape and am happy with the end result.

Questions

How big is the WIFI Module PCB?

It measures 23 × 13 mm and has 4 copper layers, 1.57 mm thick.

What parts does the WIFI Module use?

18 parts, built around the ESP8684 and Q22FA12800230. 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 WIFI Module KiCad files?

From the NEOgHacking/DMXion_4Port_Node repository on GitHub, at the commit this page was made from: the board is PCB/WIFI Module/WIFI Module.kicad_pcb and its schematic PCB/DMXion 4port node/DMX.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the WIFI Module design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
