## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA6331:1` (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/ADA6331:1.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)

## Description

Now you can quickly integrate the [Sensirion SEN6x environmental sensor node](https://blog.adafruit.com/2025/05/08/eye-on-npi-sensirion-sen66-environmental-sensor-node-eyeonnpi-digikey-digikey-sensirion-adafruit/) into your microcontroller or microcomputer project, with no soldering or fiddly breadboarding - thanks to this here **Adafruit SEN6x Adapter Breakout** (for SEN66 and friends). Adafruit covered the awesome [Sensirion SEN66 environmental sensor nodes on EYE ON NPI](https://blog.adafruit.com/2025/05/08/eye-on-npi-sensirion-sen66-environmental-sensor-node-eyeonnpi-digikey-digikey-sensirion-adafruit/) a while ago; it's an awesome all-in-one air quality sensor, but it has the annoyance that it requires 3V power/logic, and it has a special cable connection.

This adapter breakout will make an instant friendship with all SEN6x boards, thanks to a JST GH-compatible connector in the middle so that you can plug a [6-pin GH cable](https://core-electronics.com.au/jst-gh-125mm-pitch-6-pin-cable-100mm-long.html) directly between your SEN6x and this adapter. In the middle is a clean 3.3V regulator and level shifter, so you can use this module whether you're using 3.3V or 5V power and logic. [Then you can use any ol' STEMMA QT cable](https://core-electronics.com.au/jst-sh-4-pin-cable-qwiic-compatible-100mm-long.html) to plug into your Metro, Feather, QT Py, Raspberry Pi, etc, etc. I2C port.

Once you've got it plugged together, you can run Sensirion's [Arduino library](https://github.com/Sensirion/arduino-i2c-sen66) or [Raspberry Pi Python library](https://github.com/Sensirion/raspberry-pi-i2c-sen66) to read temperature, humidity, VOC, Particulate Matter PM1 / PM2.5 / PM4, and PM10. (NOx reading is also available on the SEN55)

**Please note: this board does NOT come with a JST GH-compatible cable NOR a SEN6x sensor!** You [can pick up the cable here](https://core-electronics.com.au/jst-gh-125mm-pitch-6-pin-cable-100mm-long.html), and [a SEN6x from DigiKey](https://www.digikey.com/en/product-highlight/s/sensirion/environmental-sensor-node-sen6x).
