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/COM-18354:1.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 The SparkFun Qwiic LED Stick features ten addressable APA102 LEDs, making it easy to add full color LED control using I2C. Write to individual LEDs to display a count in binary, or write to the whole strip for cool lighting effects. You can even add more LEDs to the end if you need to. We've written an Arduino library and Python package that take care of the I2C and communication to the LEDs so all you have to do is decide what color each LED should be. The LED Stick has a default I2C address of 0x23 but can be changed with a simple command, allowing you to control up to 100 LEDs (10 Qwiic LED Sticks) on a single bus! The address can also be changed to 0x22 by closing the solder jumper on the back of the board. This board is one of our many [Qwiic](https://www.sparkfun.com/qwiic) compatible boards! Simply plug and go. No soldering, no figuring out which is SDA or SCL, and no voltage regulation or translation required! **Warning:** Using a lot of LEDs can draw a lot of current. Make sure to consider the power limits of your setup. If you expect your LED chain to draw more than **600mA** of current, connect your external supply directly to VLED. Closing the jumper from VLED to VCC will add a 4.7uF decoupling capacitor. *The [SparkFun Qwiic Connect System](https://www.sparkfun.com/qwiic) is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can't hook it up wrong.* [Get Started with the Qwiic LED Stick Guide](https://learn.sparkfun.com/tutorials/1824)- 10x APA102C addressable LEDs driven by an ATTiny85 - Default I2C Address: 0x23 (Adjustable to 0x22 via Jumper) - 2x Qwiic Connectors - [Schematic](https://core-electronics.com.au/attachments/localcontent/Qwiic_LED_Stick_-_Schematic_16146d1734a.pdf) - [Eagle Files](https://core-electronics.com.au/attachments/localcontent/Qwiic_LED_Stick_20109cccd5e.zip) - [Board Dimensions](https://core-electronics.com.au/attachments/localcontent/Qwiic_LED_Stick-Dimensions_22781c831fe.png) - [Hookup Guide](https://learn.sparkfun.com/tutorials/1824) - [Datasheet](https://core-electronics.com.au/attachments/localcontent/APA102C_89597001aa0.pdf) (APA102C) - [Qwiic Information Page](https://www.sparkfun.com/qwiic) - [Qwiic LED Stick Arduino Library](https://github.com/sparkfun/SparkFun_Qwiic_LED_Stick_Arduino_Library) - [Qwiic LED Stick Python Package](https://github.com/sparkfun/Qwiic_LED_Stick_Py) - [GitHub Hardware Repository](https://github.com/sparkfun/SparkFun_Qwiic_LED_Stick) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/i/m/image_49.jpg)
