This longgg 3" x 0.8" PCB fits four Cherry MX or compatible switches and make it easy to use with a breadboard/perfboard or with a STEMMA QT (Qwiic) connector for instant I2C connectivity on any platform. ## Pricing - **Price:** $18.55 (inc GST) — $16.86 AUD, exc GST - **Quantity discounts:** 10+ $16.35 (exc GST) · 50+ $16.02 (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=ADA4980:1` (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/ADA4980:1.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 nice mechanical key is, perhaps, FOUR mechanical keys that also can glow any color of the rainbow - and that's what the Adafruit NeoKey 1x4 QT I2C Breakout will let you do! This longgg 3" x 0.8" PCB fits four Cherry MX or compatible switches and make it easy to use with a breadboard/perfboard or with a STEMMA QT (Qwiic) connector for instant I2C connectivity on any platform. The breakout has four Kailh sockets, which means you can plug in any MX-compatible switch instead of soldering it in. You may need a little glue to keep the switch in place: hot glue or a dot of epoxy worked fine for us. Each key also has a [reverse-mount NeoPixel ](https://core-electronics.com.au/neopixel-reverse-mount-rgb-leds-10-pack-of-sk6812-e.html)pointing up through the spot where many switches would have an LED to shine through. A microcontroller is pre-programmed with Adafruit's seesaw firmware so button presses and NeoPixel-controlling is done all over I2C. You can even connect multiple board by chaining the I2C and soldering closed the I2C address jumpers - with four jumpers you can have up to 16 of these boards on a single I2C bus. Adafruit have Arduino and CircuitPython/Python libraries for controlling the NeoKey 1x4's so you can use any microcontroller/computer for quick creation of a custom macropad. 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. **Please note, each order comes with one assembled and programmed PCB but no switches or keycaps**. Soldering is required to attach the header for breadboard use, you may also need to solder jumpers closed to connect multiple boards together. A microcontroller is required to drive this board, it isn't stand-alone. Keys & keycaps are not included! Use any MX-compatible switch: Kailh, Gateron, etc all work! **Technical Specifications** - Product Dimensions: 76.5mm x 21.5mm x 4.6mm / 3.0" x 0.8" x 0.2" - Product Weight: 6.0g / 0.2oz ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/4/9/4980-00.jpg)
