The Adafruit Feather ecosystem is so rich with hardware diversity, we wanted to share them, one each day. Today is the Adafruit Feather 32u4 Adalogger!
The Adafruit Feather 32u4 Adalogger is our take on an ‘all-in-one’ datalogger (or data-reader) with built in USB and battery charging. It’s an Adafruit Feather 32u4 with a microSD holder ready to rock! We have other boards in the Feather family, check’em out here
At the Feather 32u4’s heart is at ATmega32u4 clocked at 8 MHz and at 3.3V logic, a chip setup we’ve had tons of experience with as it’s the same as the Flora. This chip has 32K of flash and 2K of RAM, with built in USB so not only does it have a USB-to-Serial program & debug capability built in with no need for an FTDI-like chip, it can also act like a mouse, keyboard, USB MIDI device, etc.
The Feather 32u4 Adalogger uses extra space left over to add MicroSD + a green LED:
- Pin #8 green LED for your blinking pleasure
- MicroSD card holder for adding as much storage as you could possibly want, for reading or writing.
Comes fully assembled and tested, with a USB bootloader that lets you quickly use it with the Arduino IDE. We also toss in some header so you can solder it in and plug into a solderless breadboard.
