We call these RadioFruits, our take on a microcontroller with an RFM69HCW packet radio transceiver plus built in USB and battery charging. It's an Adafruit Feather M0 with a 900MHz radio module cooked in! Feather 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
