We designed Feather to be a new standard for portable microcontroller cores. This is the Adafruit \u003cstrong\u003eFeather M0 WiFi w\/ATWINC1500\u003c\/strong\u003e - our take on an 'all-in-one' Arduino-compatible + high speed, reliable WiFi with built in USB and battery charging. It's an Adafruit \u003cstrong\u003eFeather M0 with a WiFi module\u003c\/strong\u003e, ready to rock!\u003c\/p\u003e\n\u003cp\u003eWe have other boards in the Feather family, check'em out here.\u003c\/p\u003e\n\u003cp\u003eConnect your Feather to the Internet with this fine new FCC-certified WiFi module from Atmel. This \u003cstrong\u003e802.11bgn-capable\u003c\/strong\u003e WiFi module is the best new thing for networking your devices, with built-in low-power management capabilities, Soft-AP, SSL TLS 1.2 support and rock solid performance. We were running our adafruit.io MQTT demo for a full weekend straight with no hiccups (it would have run longer but we had to go to work, so we unplugged it). This module is very fast \u0026amp; easy to use in comparison to other WiFi modules we've used in the past.\u003c\/p\u003e\n\u003cp\u003eThis module works with \u003cstrong\u003e802.11b, g, or n networks \u0026amp; supports WEP, WPA and WPA2 encryption\u003c\/strong\u003e.  You can connect to your own WiFi networks or create your own with \"Soft AP\" mode, where it becomes its own access point (we have an example of it creating a webserver that you can then control the Arduino's pins). You can clock it as fast as \u003cstrong\u003e12MHz\u003c\/strong\u003e for speedy, reliable packet streaming. And scanning\/connecting to networks is very fast, just a second or two.\u003c\/p\u003e\n\u003cp\u003eYou might be wondering why use this when you can get a HUZZAH Feather?\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis is because, you get:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eA highly-capable Cortex M0+ processor with ton more I\/O pins, lots of 12-bit ADCs, a 10-bit DAC, 6 total SERCOMs that can each do SPI, I2C or UART (3 are used by the existing interfaces, leaving you 3), plenty of timers, PWMs, DMA, native USB, and more (check out the Datasheet)\u003c\/li\u003e\n\u003cli\u003eThe ATWINC has much lower power usage, about 12mA for the WINC \u0026amp; 10mA for the ATSAMD21 with auto-power management on for the WiFi and no power management for the ARM. With manual power management, you can get the WiFi module to down to ~2mA by putting it to sleep.\u003c\/li\u003e\n\u003cli\u003eThis is compared to the ESP's ~70mA average current draw, and whose deep sleep mode requires a WDT reset.\u003c\/li\u003e\n\u003cli\u003eWe also found that we could stream more reliably (less 'bursty') with the ATWINC, although altogether the ESP has higher throughput.\u003c\/li\u003e\n\u003cli\u003eYou also don't have to 'yield' all the time to the WiFi core, since it's a separate chip. You get full reign of the processor and timing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eOf course, both WiFi-capable Feathers have their strengths and trade-offs, \u0026amp; we love both equally!\u003c\/p\u003e\n\u003cp\u003eAt the Feather M0's heart is an \u003cstrong\u003eATSAMD21G18 ARM Cortex M0 processor\u003c\/strong\u003e, clocked at \u003cstrong\u003e48 MHz\u003c\/strong\u003e and at \u003cstrong\u003e3.3V logic\u003c\/strong\u003e, the same one used in the new Arduino Zero. This chip has a whopping \u003cstrong\u003e256K of FLASH\u003c\/strong\u003e (8x more than the Atmega328 or 32u4) and \u003cstrong\u003e32K of RAM\u003c\/strong\u003e (16x as much)! This chip comes with built in USB so it has USB-to-Serial program \u0026amp; debug capability built in with no need for an FTDI-like chip. For advanced users who are comfortable with ASF, the\u003cstrong\u003e SWDIO\/SWCLK pins are available on the bottom\u003c\/strong\u003e, and when connected to a CMSIS-DAP debugger can be used to use Atmel Studio for debugging.\u003c\/p\u003e\n\u003cp\u003eTo 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 to use a battery, it will run just fine straight from the \u003cstrong\u003emicro USB\u003c\/strong\u003e 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 through a divider to an analogue pin, so you can measure and monitor the battery voltage to detect when you need a recharge.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHere's some handy specs! Like all Feather M0's you get:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMeasures 2.1\" x 0.9\" x 0.3\" (53.65mm x 23mm x 8mm) without headers soldered in.
