Important: I have successfully ordered and assembled this project, but since then I altered the 47uF capacitor package so that it is not an extended part at JLCPCB. The author accepts NO RESPONSIBILITY for this product working, and it has not undergone extensive safety testing. Use at your own risk.
Ordering the PCB
To order the PCB at JLCPCB you will need to do the following steps:
- Submit
/gerber.zipas your job - Choose the following options:
- PCB Color: Black
- Remove Order Number: Specify a location
- Enable SMT Assembly and choose:
- Top side
- SMT QTY: 2 or 5 depending on your needs.
- Tooling holes: Added by Customer
- Confirm
- Upload files:
- BOM File:
/JLC/Controller.csv - CPL File:
/JLC/Controller-top-pos.csv
- BOM File:
- Click through to the end
- To order the top and bottom plates (high recommended), make two more orders with
plates/gerber-top.zipandplates/gerber-bottom.zip- no SMT Assembly required- PCB Thickness: Can be as low as 1.0mm but I recommend leaving it at 1.6mm
- Remove Order Number: Not necessary, I recommend No, but you could choose Yes
** MAKE SURE YOU CHOOSE THE CHEAPEST SHIPPING OPTION!! **.
Final discounts will be applied right before you pay, including free SMT Assembly. The final cost should be around $30 but it varies.

| Optional: M2 screws and nuts | 4 | You can also find these on Aliexpress, or with the above spacers in kits on Amazon, etc. To keep costs down you can use use 20 male-female standoffs, but screws + nuts (or 4x female-female standoffs) will be neater. |
Build
Soldering and construction order order I would recommend:
1. RGB headers
10x RGB pin headers should come first. You will need to remove or clip one pin from each header. To pull them out I recommend using pliers to push the pins through. You can also grab the pin with pliers and use your iron to heat it from the other side, this will free it from the plastic.
Preparing these pin headers is by far the most time consuming part of the assembly.
Protip: Place all 10 pin headers on your PCB, then place one of your spare PCBs over the top. You might want to line up the pin headers on one side, and then wiggle the binding ones until they enter the mounting holes. This will help you to get 10x headers which are nicely lined up and evenly spaced.
2. PCB standoffs
Most standoffs do not pass through the holes on the ESP32 devkit, so they will need adding to the PCB before the ESP32 devkit is soldered on top.
3. ESP32 devkit
Next, solder this to the board using the included pin headers. You might optionally want to use the standoffs to fix it to the PCB while soldering. You will also need to clip the headers after it is soldered.
4. 350211-1 Mate-N-Lok connector ("Molex connector")
Finally you can solder the power connector, make sure to use plenty of solder on this one.
5. Screw it all together
Screw on your top and bottom plates. These will be important in protecting your RGB controller and preventing shorts.
Loading the firmware
The final step is to load the firmware in accordance with instructions on the WLED wiki: https://github.com/Aircoookie/WLED/wiki

Questions
How big is the Controller PCB?
It measures 43.3 × 67.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller use?
24 parts, built around the SN74HCT245PWR(LX). 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 Controller KiCad files?
From the robhaswell/RGB-controller repository on GitHub, at the commit this page was made from: the board is Controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask robhaswell before reusing the design.
