Basic Feathers

Basic feathers are..basic. But they're not to be ignored! Their simplicity makes them a great base for Feather projects, when you don't need a wireless network, or built-in datalogging.

These were the First Feathers, as it were. They form the basis of later Feathers, so if you start here you can upgrade!

There's three chipsets available:

  • Atmel (now Microchip) ATmega32u4
  • Atmel (now Microchip) ATSAMD21
  • Freescale MK20DX256 - A.K.A Teensy 3.2, via an adapter

AVR ATmega32u4

Adafruit Feather 32u4 Basic Proto

PRODUCT ID: 2771
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....

ATmega32u4 is a well known 8-bit AVR processor, and may be more familiar to people who use the similar Arduino '328s. It's tried-and-true. The Arduino core for it was first developed in 2012 and so it's quite stable and well-known. Many low-level ATmega328 examples will work out of the box on the 32u4 (but not all!). It has 32KB of Flash and 2.5KB of RAM. It runs at 8 MHz and has native USB support

ARM ATSAMD21

Adafruit Feather M0 Basic Proto - ATSAMD21 Cortex M0

The ATSAMD21 M0 is a 32-bit Cortex M0, with a ton more flash and RAM: 256KB and 32KB. It is also supported in Arduino but is a little newer (circa ~2015) and so does not have as many years of projects and example code already. It's also a completely different chipset than the AVR, so low level code will not work and must be re-written.

That said, its about the same price and you get a ton more speed (48 MHz and 32-bit processing), and peripherals. For example you can easily create multiple hardware UARTs or I2C ports, which is impossible on the AVR. Other stuff like I2S audio, 12-bit analog input, and true analog output (DAC) is only available on this chip. Especially if you're running low on Flash, RAM, or analog inputs, this is a nice upgrade.

Teensy 3.2 Adapter

Teensy 3.x Feather Adapter

PRODUCT ID: 3200
Oh man, is this not the best thing ever? You can now use the awesome Teensy 3 with any and all of our FeatherWings or Feather accessories and even get built-in LiPoly charging! This...

It turns out the Teensy 3.2 fits right between the headers of a Feather, so we thought - hey lets make this into an adapter!
You get the awesome power, speed, and projects of the Teensy 3, with the wings of a Feather.

It's a great way to take advantage of the Feather ecosystem. You dont get everything - for example the EN pin isn't connected. But we've tested our FeatherWings so far and all are drop-in compatible.

With the space left over, we even added in a 500mA LiPoly charger that automatically charges over USB and will switch over to the LiPo when USB is unplugged. There's also a 100K resistor divider for monitoring the battery voltage connected to A7

Teensy not included, so be sure to pick one up, too!
