Great for making wireless networks that can go further than 2.4GHz 802.15.4 and similar, are more flexible than Bluetooth LE and without the high power requirements of WiFi.\u003c\/p\u003e\n\u003cp\u003eFeather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly! They designed Feather to be a new standard for portable microcontroller cores. \u003ca href=\"\/en-eu\/collections\/feather\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eWe have other boards in the Feather family, check'em out here\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis is the 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission\/reception\u003c\/strong\u003e - the exact radio frequency is determined when you load the software since it can be tuned around dynamically. \u003ca href=\"\/en-eu\/products\/adafruit-feather-32u4-rfm96-lora-radio-433mhz-radiofruit\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eWe also sell a 433MHz version of the same radio chipset!\u003c\/a\u003e And if you don't need LoRa radio, \u003ca href=\"\/en-eu\/products\/adafruit-feather-32u4-rfm69hcw-packet-radio-868-915-mhz\" target=\"_blank\" rel=\"noopener noreferrer\"\u003ewe have plain 900MHz packet radios as well\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt the Feather 32u4's heart is at ATmega32u4 clocked at 8 MHz and at 3.3V logic, a chip setup we've had tons of experience with as \u003ca href=\"\/en-eu\/products\/adafruit-flora-wearable-electronic-platform-arduino-compatible\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eit's the same as the Flora\u003c\/a\u003e. This chip has 32K of flash and 2K of RAM, with built in USB so not only does it have a USB-to-Serial program \u0026amp; debug capability built in with no need for an FTDI-like chip, it can also act like a mouse, keyboard, USB MIDI device, etc.\u003c\/p\u003e\n\u003cp\u003eTo make it easy to use for portable projects, they 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 its available. They 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.\u003c\/p\u003e\n\u003cp\u003eHere's some handy specs!
