In fact, the manufacturer Infineon suggests it could be used to make a joystick!... ## Pricing - **Price:** $10.50 (inc GST) — $9.55 AUD, exc GST - **Quantity discounts:** 10+ $9.25 (exc GST) · 50+ $9.07 (exc GST) ## Availability & dispatch - In stock, ships same business day if ordered before 2PM (Australia/Sydney). - We can dispatch 1 today, and up to 500 more in 8–12 days. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA4366:1` (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/ADA4366:1.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 TLV493D 3-axis magnetometer is a great little sensor for detecting magnets[ ***in 3D***.](https://www.youtube.com/watch?v=3FQDUX6X6-w) In fact, the manufacturer Infineon suggests it could be used to make a joystick! You could also use it for other cool things like detecting objects with magnets attached, like the lid of a box, or maybe a statue that unlocks your secret lair when placed on your mantle? The TLD493D excels at measuring nearby magnetic fields in three dimensions. It's not going to make a good compass, it's not sensitive enough to pick up the Earth's magnetic field, but you can use it to track the movement of nearby magnets in three dimensions. Here are a few specs: - Digital output via 2-wire based standard I2C interface up to 1 MBit/sec - 12-bit data resolution for each measurement direction - Bx, By and Bz linear field measurement up to +130 [mT](https://en.wikipedia.org/wiki/Tesla_(unit)) - Excellent matching of X/Y measurement for accurate angle sensing As Adafruit are wont to do, Adafruit have made the TLV easy to use by putting it on a breakout PCB along with the circuitry to support it. A voltage regulator and logic level shifting combine to make it usable with a range of microcontrollers with either 3.3V or 5V logic levels. Adafruit even give you a pin for you to use the excess 3.3V juice not needed by the TLV493D. Adafruit have also outfitted the breakout with [SparkFun Qwiic](https://core-electronics.com.au/catalogsearch/result/?q=qwiic) compatible [**STEMMA QT**](https://learn.adafruit.com/introducing-adafruit-stemma-qt) connectors to allow you to use it with other similarly equipped boards **without needing to solder.** Because the TLV493D "speaks" I2C, you only need two wires (in addition to power) to interface with your microcontroller, and you can share those pins with other I2C sensors. The manufacturer Infineon was kind enough to provide a library to use the sensor with Arduino, and Adafruit have written one to use it with CircuitPython and Python for use on Raspberry Pi and other Linux computers. ### Technical Details Product Dimensions: 25.4mm x 17.8mm x 4.6mm / 1.0" x 0.7" x 0.2" Product Weight: 1.8g / 0.1oz ![](https://core-electronics.com.au/attachments/localcontent/RoHS2_2011_65_EU_7356c5574c.svg) ![](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/4/3/4366-00.jpg)
