# Pixelblaze Sensor Expansion Board

**Type:** Product page · **SKU:** ADA5944 · **Brand:** [Adafruit](https://core-electronics.com.au/brands/adafruit-australia)
**Page:** https://core-electronics.com.au/pixelblaze-sensor-expansion-board.html ([markdown](https://core-electronics.com.au/pixelblaze-sensor-expansion-board.html.md))

The Pixelblaze Sensor Expansion Board makes it easy to write patterns that use sound, accelerometer/tilt, or light to create reactive patterns.

## Pricing

- **Price:** $63.60 (inc GST) — $57.82 AUD, exc GST
- **Quantity discounts:** 10+ $56.08 (exc GST) · 50+ $54.93 (exc GST)

## Availability & dispatch

- Out of stock — the product page offers email notification when it returns.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA5944:1` (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/ADA5944:1.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 **Pixelblaze Sensor Expansion Board** makes it easy to write patterns that use sound, accelerometer/tilt, or light to create reactive patterns. Normalized frequency data, acceleration, and light data are fed directly into your pattern as variables so you can focus on using the data instead of processing it. No libraries needed.

- A line-in jack and microphone (switches automatically), dedicated signal processing with frequency data ranging from 37Hz-10KHz designed to work in loud environments
- 32 band frequency data, amplitude, and strongest frequency detection
- 3-axis accelerometer, ±16 G per axis
- Ambient light sensor, from darkness to daylight
- 5 additional analog inputs

It's incredibly small, fitting on top of a **[Pixelblaze Standard](https://core-electronics.com.au/pixelblaze-v3-standard-xl-wifi-led-controller.html)**, or tucked away where ever you need the sensor inputs.
