Hey! It seems ur missing a lot of things, such as PCB source files, decoupling, pullups, etc. This is a cool concept, but I can only approve as t3, once these errors are fixed. Otherwise, ur BOM looks good! Why are u requesting 90 though? ur BOM comes at $63.36. Please check out https://blueprint.hackclub.com/about/submission-guidelines, and ping me if you have any questions in #blueprint-drafts!

I am planing on building this too for my school events!

The Idea

I'm helping in my schools technic team for events. And there there is a little problem with transmitting the dmx signal on a longer range. We had problems with is it, because it was going on dmx cables and its not rated for long range transmission. So this can solve this problem, because Art-Net is a LAN based protocol, so i can use ethernet cables, wifi. We also use a camsys magicdmx dongle, which only has one universe output and mine has 4 (and mine is also cheaper) . The ESP has built in wifi, so i also added a battery, so it can be wireless for smaller events, that need dmx control.

The dongle i finally replace

nice project! like iamalive said, id like to see some more detail in your journal on how you made this project. please add some info on your steps in making the pcb, the schematic, and the case. also, please move the bom.csv to the root of the repo. i really like this!

Hey! This is a cool project, but can you just fix 3 things? First, fix your bom(https://github.com/vili111111p/Art_Net_node/blob/main/PCB/BOM.csv) so it includes the price of each item/the total cost of everything. Next, include screenshots of all the components you're getting for the pcb, not just the total price and shipping option. Finally, can you split up your journal entires so its not just you saying you made the pcb? Explain how you got to the end result!

I made the case

I made the 3d model of the case. I made it like its made from two metal sheets like other small devices in stage tech. By the way it can be made from just two metal sheets with little modifications. When making the model for it i struggled a little with component 3d models not being correctly aligned on the pcb. When making the buttons i didnt really know what tolerance should i use, i hope its gonna be good.

I made the pcb design

I made the design for the PCB. I felt relieved compared to my previous project, becouse of the much bigger place i can work with. I decided to make a two layered pcb, to have a little routing challange.
Other than the routing i didnt have any other challenge i think.

I made the schematic

I made the schematic for the project. I made it so it can be powered trough POE, USB-C, and battery. I was thinking about including a powercon connector, but i dont wanna mess with high voltage. The battery is maybe a little wierd choise for a device like this, but its good, if it looses the power for some reason and becouse the esp has wifi it can be wireless for 3 or more hours in my calculations. For the ethernet input i was struggeling to find a solution, becouse making my own circuit for the w5500 i tought was a little hard, but when using a board like w5500 lite i cant really add poe. So in the end i made my own circuit and added a separet board for poe to 5v. I choose 4 universes, becouse the esp32 s3 can handle 6 or so, so it is compact and has a little room for calculations. I also wanted an interface, where i can set the universes for the dmx outputs and see the battery percentage. I could make a web interface, but thats just more power usage, but im thinking about making one.
