  • Page 4 Overview 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 cores. This is the Adafruit Feather 32u4 FONA - our take on an 'all-in-one' Arduino-compatible + audio/sms/data capable cellular with built in USB and battery charging.
  • Page 5 A 500mAh+ Lipoly battery is required for use, it keeps the cellular module happy during the high current spikes. Plug the Feather into microUSB to charge at 500mA. © Adafruit Industries https://learn.adafruit.com/adafruit-feather-32u4-fona Page 5 of 59...
