This is the Adafruit Feather M0 Bluefruit LE – our take on an all-in-one Arduino-compatible + Bluetooth Low Energy with built-in USB and battery charging. It’s an Adafruit Feather M0 with a BTLE module, ready to rock!

Bluetooth Low Energy is a hot, low-power, 2.4GHz spectrum wireless protocol. In particular, it’s the only wireless protocol that you can use with iOS without needing special certification, and it’s supported by all modern smartphones. This makes it excellent for use in portable projects that will make use of an iOS or Android phone or tablet. It also is supported in Mac OS X and Windows 8+.

At the Feather M0’s heart is an ATSAMD21G18 ARM Cortex M0 processor, clocked at 48 MHz and at 3.3V logic, the same one used in the new Arduino Zero. This chip has a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much)! This chip comes with a built-in USB so it has a USB-to-Serial program & debug capability built-in with no need for an FTDI-like chip.

To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built-in battery charging. You don’t need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when it’s available. We also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.

The Feather M0 Bluefruit LE uses the extra space left over to add our excellent Bluefruit BTLE module + two status indicator LEDs.

1. ATSAMD21G18 @ 48MHz with 3.3V logic/power

The Coral Dev Board Mini i s a single-board computer that enables you to quickly prototype and deploy an embedded system with on-device ML i nferencing. This board can also serve as an evaluation device for the C oral Accelerator Module, which allows you to i ntegrate the Edge TPU i nto your custom PCB hardware as a surface-mounted module. The Edge TPU i s a small ASIC designed by Google that accelerates TensorFlow Lite models i n a power efficient manner: each one i s capable of performing 4 trillion operations per second ( 4 TOPS), using 2 watts of power—that’s 2 TOPS per watt. For example, one Edge TPU can execute state-of-the-art mobile vision models such as MobileNet v2 at almost 400 frames per second. This on-device ML processing reduces l atency, i ncreases data privacy, and removes the need for a constant internet connection.
