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/ADA5296:1.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 only thing better than a glowy arcade button is, perhaps, FOUR glowing arcade buttons - and that's what the **Adafruit LED Arcade Button 1x4 QT I2C Breakout** will let you do! This long 3" x 0.8" PCB has 8 x [JST XH sockets that will fit Adafruit's arcade button quick connects](https://core-electronics.com.au/search/?q=quick+connect). Each XH pair lets you connect one arcade button that has a built in LED illuminator, and makes it easy to use with a breadboard/perfboard or with a STEMMA QT (Qwiic) connector for instant I2C connectivity on any platform. **Please note,** **each order comes with one assembled and programmed PCB but no [LED arcade buttons](https://core-electronics.com.au/search/?q=led+arcade) or [JST XH quick connect cables](https://core-electronics.com.au/search/?q=quick+connect).** Adafruit have a wide range of colors and sizes, so pick your favs to go along, this is just the controller board that plugs into a microcontroller. A built-in microcontroller is pre-programmed with Adafruit's seesaw firmware so button presses and LED PWM controlling is done all over I2C. You can even connect multiple board by chaining the I2C and cutting open the I2C address jumpers - with four jumpers you can have up to 16 of these boards on a single I2C bus. [Adafruit have Arduino](https://github.com/adafruit/Adafruit_Seesaw) and [CircuitPython/Python libraries](https://github.com/adafruit/Adafruit_CircuitPython_seesaw) for controlling the Arcade 1x4's so you can use any microcontroller/computer for quick creation of glowy button interfaces, without setting up PWM outputs. Adafruit found that many LEDs in buttons really want 5V power to light up, and are dim or dark at 3.3V, so they added a small boost converter to let you light up at 5V even if the microcontroller you are using is 3V power. You can also fit the breakouts onto a breadboard if you like - with two sets of breakout pads, there's plenty of flexibility for any kind of use. There are two rows of 6-pin contacts on a 0.1" grid on both sides. Solder in both sides for mechanical stability. Soldering is required to attach the header for breadboard use, if you have STEMMA QT/Qwiic connectors its a simple plug-in to get working. **A microcontroller is required to drive this board, it isn't stand-alone. [LED arcade buttons](https://core-electronics.com.au/search/?q=led+arcade) and [JST XH quick connect cables](https://core-electronics.com.au/search/?q=quick+connect) not included!** ## Technical Details Default I2C address 0x3A Product Dimensions: 76.3mm x 21.5mm x 13.0mm / 3.0" x 0.8" x 0.5" Product Weight: 9.6g / 0.3oz ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/i/m/image_12341.jpg)
