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/ADA5309:1.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 The MSA311 is a super small and low-cost **triple-axis accelerometer**. It's inexpensive, but has just about every 'extra' you'd want in an accelerometer: - Three-axis sensing, 14-bit resolution - ±2g/±4g/±8g/±16g selectable scaling - I2C interface on fixed I2C address 0x62 - Interrupt output - Multiple data rate options 1 Hz to 500 Hz - As low as 2uA current draw in low power mode (just the chip itself, not including any supporting circuitry) - Tap, Double-tap, orientation & freefall detection **The MSA311 is *very similar* to the MSA301, but is not a drop-in replacement. The I2C address has changed from 0x26 to 0x62!** This sensor communicates over I2C or SPI (our library code supports both) so you can share it with a bunch of other sensors on the same I2C bus. There's an address selection pin so you can have two accelerometers share an I2C bus. To get you going fast, Adafruit spun up a custom-made PCB in the[ **STEMMA QT** form factor](https://core-electronics.com.au/search/?q=stemma%20qt%20sensor), making them easy to interface with. The [STEMMA QT connectors](https://learn.adafruit.com/introducing-adafruit-stemma-qt/what-is-stemma-qt) on either side are compatible with the [SparkFun Qwiic](https://core-electronics.com.au/catalogsearch/result/?q=qwiic) I2C connectors. This allows you to make solderless connections between your development board and the MSA311 or to chain with a wide range of other sensors and accessories using a [**compatible cable**](https://core-electronics.com.au/search/?q=stemma%20qt%20cable). [QT Cable is not included, but Adafruit have a variety in the shop](https://core-electronics.com.au/search/?q=stemma+qt+cable) We’ve of course broken out all the pins to standard headers and added a voltage regulator and level shifting so allow you to use it with either 3.3V or 5V systems such as the Raspberry Pi + Feather series or Arduino Uno respectively. Comes with a bit of 0.1" standard header in case you want to use it with a breadboard or perfboard. Four mounting holes for easy attachment. ## Technical Details Product Dimensions: 25.2mm x 17.7mm x 4.6mm / 1.0" x 0.7" x 0.2" Product Weight: 1.7g / 0.1oz ![RoHS 2 2011 65 EU Compliant](https://core-electronics.com.au/attachments/localcontent/RoHS2_2011_65_EU_7356c5574c.svg)![RoHS 2 2015 863 EU Compliant](https://core-electronics.com.au/attachments/localcontent/RoHS2_2015_863_EU_86773f57f9.svg) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/i/m/image_12282.jpg)
