## Pricing

- **Price:** $15.70 (inc GST) — $14.27 AUD, exc GST
- **Quantity discounts:** 6+ $13.56 (exc GST) · 12+ $12.99 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 2 today, and up to 250 more in 8–12 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0529:1` (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/SEN0529:1.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

**BMM150 is a low-power and low-noise 3-axis geomagnetic sensor from Bosch for compass applications.** It allows measurements of the magnetic field and compass angle in three perpendiculars within a measuring range of ±1300uT on X and Y axis and ±2500uT on Z axis.

Featuring small size and lightweight, the sensor has a 2-bit DIP switch for I2C address setup, and 4 addresses are available. Based on Bosch's proprietary FlipCore technology, the performance and features of BMM150 are carefully tuned and thus can offer absolute spatial orientation without calibration, perfectly matching the requirements of all 3-axis mobile applications such as robot navigation & positioning, electric compass, electric map, navigation or augmented reality.
