Adafruit Feather M0 RFM69HCW Packet Radio - 868 or 915 MHz (RadioFruit) _ARD 6-pin ISP header for direct

6-pin ISP header for direct programming (also pre-loaded with Arduino bootloader)

Wire gauge is 22 AWG which we've found is the best all-around gauge

It offers a generous 256 KB of Flash (eight times more than an ATmega328 or ATmega32u4) and 32 KB of RAM (sixteen times more)

Adafruit Feather M0 RFM69HCW Packet Radio - 868 or 915 MHz (RadioFruit) _ARD 6-pin ISP header for directThis is the Adafruit Feather M0 RFM69 Packet Radio (868 or 915 MHz). We call these RadioFruits, our take on an microcontroller with a RFM69HCW packet radio transceiver plus built in USB and battery charging. Its 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
