e.g. ws2812b, and only tested with them
The Power supply is a 100-240VAC one and rated at 5v 4A, don't exceed the power of the supply. Use e.g. the WLED power calculator
As i live in germany, the pcb is only tested with 230V AC, if you supply any other voltage, be warned!
It can go up in flames, explode or kill you. It's main power!

For the Cable Holes i added some Rubber Cable Rings with 6mm inner diameter
Assembly
- Order the pcb at e.g. pcbway or jlcpcb
- While you wait, Print the casing
- Assemble the PCB
- use a soldering iron to mount your threaded inserts in the case
- mount the rubber rings, if you brought them
- Check your usb 2 serial converter that it is set to 3.3V (any other voltage will damage the esp8266)
- use the pcb pin headers to wire up the PCB with the usb 2 serial converter
