# 1. Buying Hardware
## Controller
For each Luxio LED Strip, you need a single [Wemos LOLIN D1 mini V4](https://www.wemos.cc/en/latest/d1/d1_mini.html). These are only a few dollars on AliExpress.
## LED Strip
Luxio works exclusively with any WS2812b LED Strip.
These are digital, individual-addressable LEDs placed on a strip varying in length — usually between 1 meter and 5 meter.
You can configure the number of LEDs for every Luxio, so you can buy varying lengths. Just keep note of the power usage.
## USB-C Cable
Any USB-C cable that transmits power should work, but keep mind that some have bad quality.

## USB-C Adapter
Any 5V USB-C adapter will work, but it depends on the number of LEDs how much Ampere (A) you need.
The LOLIN D1 mini requires `200 mA`.
As a rule of thumb, every LED requires `50 mA` (that's `0.05 A`) when it's full-brightness and white.
For example, for a 2-meter LED Strip with 120 LEDs, you need `0.2 A + 0.05 ⨉ 120 = 6.2 A`.
As you can see, that's a lot and these adapters are very rare to come by! Regular adapters are only about 2 A. However, in the real world, these adapters perform quite well, because your LED-strip is rarely full-brightness and white — which uses most power.
In our example, a `3 A` adapter would work fine.
