But you don't need... ## 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=ADA4400:1` (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/ADA4400:1.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 Machine learning has come to the 'edge' - small microcontrollers that can run a very miniature version of TensorFlow Lite to do ML computations. But you don't need super complex hardware to start developing your own TensorFlow models! Adafruit have adapted Adafruit's popular PyBadge board to add a microphone so you can dip your toes into machine learning waters. It does everything that the PyBadge does, and as Adafruit make more projects that use Machine Learning we'll adapt this board to make it better and better for machine learning. The EdgeBadge is a compact board - it's credit card sized. It's powered by Adafruit's favorite chip, the ATSAMD51, with 512KB of flash and 192KB of RAM. Adafruit add 2 MB of QSPI flash for file storage, handy for TensorFlow Lite files, images, fonts, sounds, or other assets. Adafruit have added a PDM microphone on the front as an input for micro speech recognition. Adafruit's Arduino library has some demos you can get started with to recognize various word pairs like "yes/no", "up/down" and "cat/dog". **TensorFlow Lite for microcontrollers is very cutting-edge so expect to see a lot of development happening in this area, with lots of code and process changes.** [Here's a list of everything you get with the EdgeBadge. Since its a PyBadge+Microphone you can read a lot more about it on the product page](https://core-electronics.com.au/adafruit-pybadge-for-makecode-arcade-circuitpython-or-arduino.html) - **ATSAMD51J19** @ 120MHz with 3.3V logic/power - 512KB of FLASH + 192KB of RAM - **2 MB of SPI Flash** for storing images, sounds, animations, whatever! - **1.8" 160x128 Color TFT Display** connected to its own SPI port - **8 x Game/Control Buttons** with nice silicone button tops (these feel great) - **5 x NeoPixels** for badge dazzle, or game score-keeping - **Triple-axis accelerometer** (motion sensor) - **Light sensor**, reverse-mount so that it points out the front - **Built in buzzer mini-speaker** - **Mono Class-D speaker driver** for 4-8 ohm speakers, up to 2 Watts - LiPoly battery port with built in recharging capability - USB port for battery charging, programming and debugging - Two female header strips with Feather-compatible pinout so you can plug any FeatherWings in - JST ports for NeoPixels, sensor input, and I2C (you can fit I2C Grove connectors in here) - Reset button - On-Off switch ### Technical Details Product Dimensions: 86.3mm x 54.3mm x 13.6mm / 3.4" x 2.1" x 0.5" Product Weight: 29.6g / 1.0oz ![](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/a/d/ada4400-1.jpg)
