## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0622:1` (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/SEN0622:1.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

The Fermion: BMM350 3-axis geomagnetic sensor is designed to measure magnetic fields across three vertical axes and functions as a compass. Utilising Bosch's patented FlipCore technology, this sensor provides accurate spatial orientation without the need for calibration. It maintains compatibility with [the previous BMM150 series](https://www.dfrobot.com/product-2626.html) while delivering enhanced performance, including lower power consumption and improved measurement capabilities. The BMM350 is powered by the groundbreaking TMR (tunnel magnetoresistance) technology, coupled with a distinctive field shock recovery feature that fortifies the device against interference from external magnetic fields, guaranteeing consistent high-precision measurements.

**Field Shock Recovery for Stable Performance**

The BMM350 is equipped with a robust field shock recovery function, powered by TMR technology. This ensures that the sensor maintains high performance even when exposed to external magnetic field disturbances. The shock recovery feature allows the sensor to provide consistent, reliable data in challenging environments, making it well-suited for use in mobile or dynamic systems.

**High Sample Rate for Real-Time Data**

Supporting a high sample rate of up to 400Hz, the BMM350 is capable of providing real-time, precise data critical for applications that demand rapid response times, such as AR/VR systems, geomagnetic navigation in AGVs, and drone flight control. The high sample rate ensures accurate spatial orientation and movement tracking.

**Wide Measurement Range and High Resolution**

With a measurement range of ±2000µT across all three axes (XYZ), the BMM350 can accurately capture magnetic fields over a broad spectrum. This expanded range is complemented by a high resolution of 0.1µT, allowing the sensor to detect even the smallest fluctuations in the magnetic field. This makes it ideal for high-precision applications in advanced technology systems.
