Single transistor PNP Emitter Follower contribution @Robin

Use of a level shifter solves the issue of a leading GRN LED being seen with an RGB strip. The leading edge of the data sent for the RED component is crunched below the 70% threshold, preventing it turning on, thereby revealing GRN instead.

Power Supply Considerations

Use a separate supply to power Neopixels. Use a level shifter at the data signal output pin.

Each individual Neopixel at full brightness will require around 20mA for each color element. The 24bit RGB will require 60mA and the 32bit RGBW will require 80mA. Driving more than one or possibly two of these individual Neopixels directly from an Espruino device may likely damage the onboard regulator.

Driving just 12 RGBW or 16 RGB will require 960mA and will need an external 5V 1 amp supply.
As P = I E the supply will be dissipating 5 Watts. Yes, things will get warm.

12V Automotive single color LED strips

The following links are provided for reference only, as considered too basic a discussion for this individually addressable LED strip REFERENCE page, as software and a microcontroller aren't necessarily required to drive the single color LED strips.

Purchasing Considerations

It is strongly recommended to vet the website supplier before making a purchase. Insist on and review the datasheet prior to the order. Many overseas discount shopping cart sites are created by mom-and-pop outfits that may have no knowledge on what they actually are selling. Review the title and description in detail and compare with the datasheet. Fail to do so, and you may receive a variant as indicated in the first link 'Original thread discussion' above. I just checked (2020.03.01) the outbound link within that discussion, and the site pointed to, still advertises the incorrect type and here we are one year later! caveat emptor

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

> Quote text by starting lines with >

Mention another user by @username

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
