Adafruit’s FLORA is designed around the ATMEGA32U4 microcontroller with 3.3 V logic and has built-in USB and USB HID support allowing it to act as a mouse or keyboard to attach directly to computers. It is easily programmed over USB using the Arduino IDE and has a small but easy to use onboard reset button to reboot the system. The onboard power supply is designed to be flexible and easy to use with an onboard-polarized 2-pin JST battery connector with Schottky diode protection for use with external battery packs from 3.5 V to 16 V DC and power switch connected to 2 A power FET for safe and efficient battery on/off control. Designed with a thoughtful layout, data buses are interleaved with power and ground pads for easy module and sensor attachments without worrying about overlapping traces.
