Adafruit Feather M0 WiFi combines a SAM D21 and ATWINC1500


Oh my, an Adafruit Feather with Wi-Fi! 


Makers, meet the Adafruit Feather M0 WiFiAs its name would suggest, the all-new board is Adafruit’s latest take on an Arduino-compatible, ‘all-in-one’ platform with high-speed Wi-Fi connectivity, USB support and a built-in battery charger.

Equipped with an Atmel | SMART SAM D21 and ATWINC1500 SoC at its core, Makers will find it super simple to connect their Feathers to the Internet. The 802.11bgn-capable Wi-Fi module is the ideal add-on to existing MCU solutions bringing wireless and network capabilities through UART or SPI-to-Wi-Fi interface.

“This module works with 802.11b, g, or n networks and supports WEP, WPA and WPA2 encryption,” Adafruit writes. “The datasheet says it can do Soft-AP mode but we don’t have any code to actually use that. You can clock it as fast as 12MHz for speedy, reliable packet streaming. And scanning/connecting to networks is very fast, a few seconds.”

The ATSAMD21G18 Cortex-M0+ processor at its heart — which is the same chip used in the new Arduino Zero — is clocked at 48MHz and at 3.3V logic. It boasts a whopping 256K of Flash (eight times more than the Atmega328 or 32u4) and 32K of RAM (16 times as much). The MCU comes with native USB, as well as a USB bootloader and serial port debugging.

With portability in mind, Adafruit has included a connector for any 3.7V LiPo battery along with an integrated charger. Even without a battery, it will run just fine via microUSB. The Feather will even automatically switch over to USB power when it’s available.

“We also tied the battery through a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge,” Adafruit writes.

The ‘M0 WiFi features a similar form factor as many of its other Feathers, measuring 2.1″ x 0.9″ x 0.3” in size and weighing 6.1 grams. (Note, however, that it is 0.1″ longer than its siblings.) Beyond that, the board has 20 GPIO pins with eight PWM pins, 10 analog inputs, a single analog output, a power/enable pin, four mounting holes and a reset button. Plus, there are a couple of LEDs and is compatible with a wide range of FeatherWings, including OLED, NeoPixels, servos, relays, seven-segment displays, etc.
