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/CE10107:1.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 PiicoDev® Magnetometer measures invisible magnetic fields. It's sensitive enough to use as a compass and wide-range enough for detecting magnets - which have a much stronger field. The on-board MMC5603 can measure 20-bits in up to 3000μT in all 3 axes. By using PiicoDev adapters and cables, you can connect to this sensor without soldering - or use the standard breakout header if you prefer breadboard prototyping. Whichever you prefer, the PiicoDev [guides](https://core-electronics.com.au/guides/piicodev/diy-magnetic-encoder/) will guide you through exciting experiments like measuring the Earth's magnetic field to find a heading and detecting if a magnet is nearby. **Features** - Small size, high accuracy - Measures magnetic fields in 3-axes - Sensitive enough to use like a compass, broad range enough to work with nearby magnets - Great guides to get you started - PiicoDev connector, compatible with Qwiic and STEMMA QT (3.3V only) - 2.54mm breakout for breadboarding/prototyping - Manufactured and [supported](https://core-electronics.com.au/contacts/) in Australia by Core Electronics **Getting Started Guides** We've prepared a [getting-started guide](https://core-electronics.com.au/guides/piicodev-magnetometer-getting-started-guide/) that works with Raspberry Pi, Pico, and Micro:bit. **Technical Specifications** - Address: 0x30 - 3-axis, 20-bit precision per channel - Dimensions: 25.4x25.4mm - Mounting Holes: 2x M2.5 **Resources** - [Hardware Repo](https://github.com/CoreElectronics/CE-PiicoDev-Magnetometer-MMC5603) - [Schematic](https://github.com/CoreElectronics/CE-PiicoDev-Magnetometer-MMC5603/raw/main/Documents/PiicoDev%20Magnetometer%20MMC5603.pdf) - [Datasheet: QMC6310](https://github.com/CoreElectronics/CE-PiicoDev-Magnetometer-MMC5603/raw/main/Documents/MMC5603_datasheet.pdf) - [Example code](https://github.com/CoreElectronics/CE-PiicoDev-MMC5603-MicroPython-Module) - [Mounting Guide](https://core-electronics.com.au/tutorials/piicodev-mounting-guide.html) Also available are [PiicoDev Starter Kits](https://core-electronics.com.au/piicodev.html#category_1322) - level up your projects by learning how to use a wide range of modern sensors and outputs. ![](https://core-electronics.com.au/media/wysiwyg/CE10107-PiicoDev-Magnetometer-MMC5603.jpg)![](https://core-electronics.com.au/media/wysiwyg/CE10107-PiicoDev-Magnetometer-MMC5603.jpg) ## Guides for this product - [PiicoDev Magnetometer- Getting Started Guide](https://core-electronics.com.au/guides/piicodev/piicodev-magnetometer-getting-started-guide/) - [How to add GPS to a Raspberry Pi Pico \| Get Real-Time Location in Your Project!](https://core-electronics.com.au/guides/raspberry-pi-pico/how-to-add-gps-to-a-raspberry-pi-pico/) ## Videos for this product - [How to add GPS to a Raspberry Pi Pico \| Get Real-Time Location in Your Project!](https://core-electronics.com.au/videos/how-to-add-gps-to-a-raspberry-pi-pico-get-real-time-location-in-your-project) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/c/e/ce10107-piicodev-magnetometer-mmc5603-hero.jpg)
