# Triple Axis Accelerometer BMA220 (Tiny)

**Type:** Product page · **SKU:** SEN0168 · **Brand:** [DFRobot](https://core-electronics.com.au/brands/dfrobot-australia)
**Page:** https://core-electronics.com.au/triple-axis-accelerometer-bma220-tiny.html ([markdown](https://core-electronics.com.au/triple-axis-accelerometer-bma220-tiny.html.md))

This Triple Axis Accelerometer with Bosch BMA220 is an ultra small triaxial, low-g acceleration sensor breakboard with SPI and I2C interface, aiming for lowpower consumer market applications. It allows measurement of accelerations in 3 perpendicular axes and thus senses tilt, motion, shock and vibration in cell phones, handhelds, computer peripherals, man-machine interfaces, virtual reality features and game controllers.

## Pricing

- **Price:** $7.70 (inc GST) — $7.00 AUD, exc GST
- **Quantity discounts:** 6+ $6.65 (exc GST) · 12+ $6.37 (exc GST)

## Availability & dispatch

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0168:1` (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/SEN0168:1.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

**Introduction**

 This Triple Axis Accelerometer with Bosch BMA220 is an ultra small triaxial, low-g acceleration sensor breakboard with SPI and I2C interface, aiming for lowpower consumer market applications. It allows measurement of accelerations in 3 perpendicular axes and thus senses tilt, motion, shock and vibration in cell phones, handhelds, computer peripherals, man-machine interfaces, virtual reality features and game controllers. With a size of only 2 mm x 2 mm, the Bosch BMA220 represents a new generation of acceleration sensors. The Tri-Axis Accelerometer integrates a multitude of features that acilitates its use especially in the area of motion detection applications, such as device orientation detection, gaming, HMI and menu browser control. It is highly configurable in order to give the designer full flexibility when integrating the sensor into his system. It can be used in sensing tilt, motion and shock vibration in mobile devices, handhelds, digital peripherals, man-machine interfaces, virtual reality features and game consoles. Note: Recommend to connect the sensor to 3.3v powered microcontroller. Though it directly works with Arduino UNO/Leonardo(System working voltage: 5v). **Specification**
