Well, Adafruit can help with that - get a CLUE here at Adafruit by picking up this sensor-packed development board ## Pricing - **Price:** $86.60 (inc GST) — $78.73 AUD, exc GST - **Quantity discounts:** 10+ $76.36 (exc GST) · 50+ $74.79 (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=ADA4500:1` (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/ADA4500:1.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 Do you feel like you just don't have a CLUE? Well, Adafruit can help with that - get a CLUE here at Adafruit by picking up this sensor-packed development board. Adafruit wanted to build some projects that have a small screen and a lot of sensors. To make it compatible with existing projects, Adafruit made it the [same shape and size as the BBC micro:bit](https://core-electronics.com.au/#) and with the same edge-connector on the bottom with 5 big pads so it will fit into your existing robot kit or 'bit add-on. While the CLUE looks a bit like a 'bit it has totally redesigned-from-scratch technology: - **Nordic nRF52840 Bluetooth LE processor** - 1 MB of Flash, 256KB RAM, 64 MHz Cortex M4 processor - **1.3" 240×240 Color IPS TFT display** for high resolution text and graphics - **Power it from any 3-6V battery source** (internal regulator and protection diodes) - **Two A / B user buttons** and one reset button - Tons of sensors! - ST Micro series 9-DoF motion - [LSM6DS33 Accel/Gyro](https://core-electronics.com.au/adafruit-lsm6ds33-6-dof-accel-gyro-imu-stemma-qt-qwiic.html) + [LIS3MDL](https://core-electronics.com.au/adafruit-triple-axis-magnetometer-lis3mdl-stemma-qt-qwiic.html)[ magnetometer](https://core-electronics.com.au/adafruit-triple-axis-magnetometer-lis3mdl-stemma-qt-qwiic.html) - [APDS9960 Proximity, Light, Color, and Gesture Sensor](https://core-electronics.com.au/adafruit-apds9960-proximity-light-rgb-and-gesture-sensor.html) - [PDM Microphone sound sensor](https://core-electronics.com.au/adafruit-pdm-mems-microphone-breakout.html) - [SHT Humidity](https://core-electronics.com.au/sht-30-mesh-protected-weather-proof-temperature-humidity-sensor-1m-cable.html) - [BMP280 temperature and barometric pressure/altitude](https://core-electronics.com.au/adafruit-bmp280-i2c-or-spi-barometric-pressure-altitude-sensor.html) - **RGB NeoPixel** indicator LED - **2 MB internal flash storage** for datalogging, images, fonts or CircuitPython code - **Hardware SPI, UART, I2C, and I2S** on any pins - **Buzzer/speaker** for playing tones and beeps - **Two bright white LEDs** in front for illumination / color sensing. - **Qwiic / STEMMA QT connector** for adding more sensors, motor controllers, or displays over I2C. [You can plug in GROVE I2C sensors by using an adapter cable](https://core-electronics.com.au/4-pin-jst-ph-to-jst-sh-cable-stemma-to-qt-qwiic-200mm-long.html). - **Programmable with Arduino IDE or CircuitPython** Please note that at this time there is **no MakeCode or Scratch support** for the nRF52840 chipset (of course, we’d love to see MakeCode but there is no ETA when it may be added). While the CLUE is the same outline and Adafruit did Adafruit's best to make the edge-connector pins match up, most cases for the 'bit won't fit the CLUE, and code may not be immediately compatible without adjustment, especially since only Arduino and CircuitPython are supported at this time. The CLUE is designed for projects that use a ton of sensors - and they're all built-in! So you can start exploring your world, measuring, logging, and learning. You can transmit data over Bluetooth to a computer or mobile device for data plotting and logging, or save it to the built-in storage. [Why did Adafruit call it CLUE?

The design is otherwise identical to ALPHA (hardware, shape, pinout, etc) Product Dimensions: 51.7mm x 42.2mm x 12.3mm / 2.0" x 1.7" x 0.5" Product Weight: 13.0g / 0.5oz ![RoHS 2 2011 65 EU Compliant](https://core-electronics.com.au/attachments/localcontent/RoHS2_2011_65_EU_7356c5574c.svg)![RoHS 2 2015 863 EU Compliant](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/a/d/ada4500-2.jpg)
