In the last year, I made simple PCB Christmas tree

This year I discovered an open source project - WLED and I will to use WLED to make this year's Christmas tree

version

Supplies

The 23 LEDs version uses 5050 size WS2812B LED

The advantage is that it is easy to make

The 41 LEDs version uses a smaller 2020 size WS2812B LED

More effects can be displayed, but the LED is too small, which means that the soldering process will be much more difficult

Step 1: Schematic

23 LEDs version

Custom PCB x 1
WS2812B - 5050 X 23
100nF Capacitor x 8
10K Ohms resistance x 1
Infrared remote receiver X 1
Push button switch X 1
8 Pin Header X 1

41 LEDs version

Custom PCB x 1
WS2812B - 2020 X 41
100nF Capacitor x 8
10K Ohms resistance x 1
Infrared remote receiver X 1
Push button switch X 1
8 Pin Header X 1

core part

Wemos D1 mini
Wemos D1 mini Dual Base Shield
21Key Infrared remote control

Step 2: PCB

The PCB Christmas tree continues to use the previous year's design. Using D1 mini Dual Base Shield，Let the Christmas tree stand up.

I use EasyEDA to design PCB and upload the design to JLCPCB.com to manufacture PCB.

JLCPCB make high quality prototyping PCBs for people all over the world. They have over 300,000 worldwide customers with over 8000 orders per day! They have over 10 years of manufacturing experience and are super reliable. Try it for your self and get 10 PCBs for just $2 at JLCPCB, New registered users US$54 offer , Order here

You can use my gerber files to ordel your own PCBs, and build this DIY Project.

Just a quick example how to order PCB from JLCPCB.com:

1)press "QUOTE NOW"

2)press "Add your gerber files"

3)upload zip or rar

4)all properties could be left default
