A simple 3 Degrees of Freedom accelerometer breakout that measures acceleration in three axes - X, Y, and Z. If you need simple and reliable motion detection for your project, then this is a great choice!

## Pricing

- **Price:** $14.15 (inc GST) — $12.86 AUD, exc GST
- **Quantity discounts:** 10+ $12.35 (exc GST) · 25+ $11.96 (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=CE06457:1` (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/CE06457:1.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

This accelerometer has a few nifty features built-in too. It has interrupted for motion in each axis, double-tap detection, and freefall detection. This built-in support means that you can detect each of these types of motion with a single line of code, rather than having to code a whole function yourself.

The MSA301 3DoF breakout has an I2C interface and is 3.3V or 5V compatible. Like Pimoroni's other [Pimoroni breakouts](https://core-electronics.com.au/search/?q=pimoroni+breakouts), Pimoroni has designed it so that you can solder a piece of right-angle header onto it and then pop it straight onto the bottom left 5 pins on your Raspberry Pi's GPIO header (pins 1, 3, 5, 6, 9).

It's also compatible with Pimoroni's fancy [Breakout Garden,](https://core-electronics.com.au/breakout-garden-hat.html) where using breakouts is as easy as just popping it into one of the six slots and starting to grow your project, create, and code.
