TensorFlow Lite for Microcontrollers Kit PRODUCT ID: 4317 Machine learning has come to the 'edge' - small microcontrollers that can run a very miniature version of Tensor Flow Lite to do ML computations. But you don't need super complex hardware to start developing your own TensorFlow models! We've curated a simple kit to dip your toes into machine learning waters. Kit includes: Adafruit PyBadge with SAMD51 Cortex M4F processor @ 120MHz, with display, speaker and buttons Electret Microphone Amplifier - MAX4466 with Adjustable Gain JST PH 3-Pin to Female Socket Cable - 200mm Lithium Ion Polymer Battery wi th Short Cable - 3.7V 350mAh
The kit uses our PyBadge as your edge processor. It's a co mpact board - it's credit card sized. It's powered by ou r favorite chip, the ATSAMD51, with 512KB of flash and 192KB of RAM. We add 2 MB of QSPI flash for fi le storage, handy for TensorFlow Lite files, images, fonts, sounds, or other assets. You can plug in a microphone into the ports at the bottom, to add microphone input for micro speech re cognition. Our Ar duino library has some demos you can get st arted with to recognize various word pairs like "yes/no", "up/down" and "cat/dog". Tensor Flow 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. Some light soldering is required to attach the microphone headers onto the board. Here's a list of everything you get with the PyBadge, you can read a lot more about it on the product page ATSAMD51J19 @ 120MHz wi th 3.3V logic/power - 512KB of FLASH + 192KB of RAM 2 MB of SPI Flash for storing imag es, sounds, animations, whatever! 1.8" 160x128 Color TFT Display connected to its own SPI port 8 x Game/Control Buttons with nice silicone butt on 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 bu ilt in recharging capability USB port for battery charging, programming and debugging Two female header strips with Feat her-compatible pinout so you can plug any FeatherWings in JST ports for NeoPixels, sensor inpu t, and I2C (you can fit I2C Grove connectors in here) Reset button On-Off switch
