We call these RadioFruits, our take on an microcontroller packet radio transceiver with built in USB and battery charging. Its an Adafruit \u003cstrong\u003eFeather 32u4 with a 900 MHz radio module cooked in\u003c\/strong\u003e! 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! We designed Feather to be a new standard for portable microcontroller cores.\u003c\/p\u003e\n\u003cp\u003eWe have other boards in the Feather family, check'em out here.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis is the 900 MHz radio version\u003c\/strong\u003e, which can be used for either \u003cstrong\u003e868MHz 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. We also sell a 433MHz version of the same radio chipset and if you want much longer range, check out the LoRa 900MHz Feather.\u003c\/p\u003e\n\u003cp\u003eAt the Feather 32u4's heart is at \u003cstrong\u003eATmega32u4\u003c\/strong\u003e clocked at \u003cstrong\u003e8 MHz\u003c\/strong\u003e and at \u003cstrong\u003e3.3V logic\u003c\/strong\u003e, a chip setup we've had tons of experience with as it's the same as the Flora. This chip has \u003cstrong\u003e32K of flash\u003c\/strong\u003e and \u003cstrong\u003e2K of RAM\u003c\/strong\u003e, with \u003cstrong\u003ebuilt in USB\u003c\/strong\u003e 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, we added a \u003cstrong\u003econnector for any of our 3.7V Lithium polymer\u003c\/strong\u003e 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. We also tied the battery thru 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!
