Adafruit has this week unveiled a new development board they have created called Feather which as the name suggests is a thin and lightweight board and has been designed to provide users with a portable micro controller core.
The Feather 32u4’s is equipped with an ATmega32u4 clocked at 8 MHz and at 3.3V logic, a chip setup, together with 32K of flash and 2K of RAM.
To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don’t need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge.
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. This chip is well supported in the Arduino IDE and can run just about every sensor/library out there.
Features of the Feather 32u4 Basic Proto microcontroller include :
• Measures 2.0″ x 0.9″ x 0.28″ (51mm x 23mm x 8mm) without headers soldered in
• Light as a (large?) feather – 4.8 grams
• ATmega32u4 @ 8MHz with 3.3V logic/power
• 3.3V regulator with 500mA peak current output
• USB native support, comes with USB bootloader and serial port debugging
• You also get tons of pins – 20 GPIO pins
• Hardware Serial, hardware I2C, hardware SPI support
• 8 x PWM pins
• 10 x analog inputs (one is used to measure the battery voltage)
• Built in 100mA lipoly charger with charging status indicator LED
• Pin #13 red LED for general purpose blinking
• Power/enable pin
• 4 mounting holes
• Reset button
