Great for making wireless networks that are more flexible than Bluetooth LE and without the high power requirements of WiFi.\u003c\/p\u003e\n\u003cp\u003eFeather is the development board specification from Adafruit, and like its namesake, it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores.

You get all the pins for use on the Feather, the Lipoly battery support, USB C power \/ data, onboard NeoPixel, 8MB of FLASH for storing code and files, and then with the 8 unused pins, we wired up all the DIO pins on the RFM module. There's even room left over for a STEMMA QT connector an a uFL connector for connecting larger antennas.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis is the 900 MHz RFM69 packet 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. Despite calling it a 'packet' radio (and it does send packets of data) the RFM69 can also be used for non-packetized radio transmission and reception.\u003c\/p\u003e\n\u003cp\u003eAt the Feather's heart is an RP2040 chip, clocked at 133 MHz and at 3.3V logic, the same one used in the \u003ca href=\"\/en-eu\/products\/raspberry-pi-pico\" target=\"_blank\"\u003eRaspberry Pi Pico\u003c\/a\u003e. This chip has a whopping 8MB of onboard QSPI FLASH and 264K of RAM! This makes it great for making wireless sensor nodes that can send to each other without a lot of software configuration.\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 a battery, it will run just fine straight from the USB Type C 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHere're some handy specs!
