Make your own smart LED arrangement with the same integrated LED that is used in our NeoPixel strips and pixels. We use this same LED in our Metro M4 Express and Neo TrinKey. ## Pricing - **Price:** $35.45 (inc GST) — $32.23 AUD, exc GST - **Quantity discounts:** 10+ $31.26 (exc GST) · 50+ $30.62 (exc GST) ## Availability & dispatch - Out of stock — the product page offers email notification when it returns. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA4957:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA4957:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description ## Description Itsy Bitsy Teenie Weenie **Mini NeoPixel RGB LED**inis! Make your own smart LED arrangement with the same integrated LED that is used in Adafruit's NeoPixel strips and pixels. Adafruit use this same LED in Adafruit's [Metro M4 Express](https://core-electronics.com.au/adafruit-metro-m4-feat-microchip-atsamd51.html) and [Neo TrinKey](https://core-electronics.com.au/adafruit-neo-trinkey-samd21-usb-key-with-4-neopixels.html). These **MINI** (3.5mm x 3.5mm) RGB LEDs are fairly easy to solder and are *half* the size of the standard 5x5mm NeoPixels you may be used to seeing. They're one of the most compact ways possible to integrate multiple bright LEDs into a design. The driver chip is inside the LED and has a constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors **This is the Pack of 100 NeoPixel Mini RGB LEDs with a Black Casing.** Don't need so many? They also have [10-pack minis in black casing](https://core-electronics.com.au/neopixel-mini-3535-rgb-leds-w-integrated-driver-chip-black-pack-of-10.html) and [white casing here](https://core-electronics.com.au/neopixel-mini-3535-rgb-leds-w-integrated-driver-chip-white-pack-of-10.html). These come in a cut tape strip so can be used in a feeder if a leader is taped on. The LEDs are 'chainable' by connecting the output of one chip into the input of another - see the datasheet for diagrams and pinouts. To allow the entire chip to be integrated into a 4-pin package, there is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microcontroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the Netduino or Basic Stamp. [The LEDs basically have a WS2811 inside, but fixed at the 800KHz 'high speed' setting.](https://core-electronics.com.au/ws2811-led-driver-chip-10-pack.html) Adafruit's wonderfully-written [NeoPixel library for Arduino supports these pixels!](https://github.com/adafruit/Adafruit_NeoPixel) As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required. [Adafruit have a ready-to-go component for this in the Adafruit EAGLE library](https://github.com/adafruit/Adafruit-Eagle-Library) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/4/9/4957-00.jpg)
