Overview

Wouldn't it be great if, instead of collecting shields, HATs, PMODs, Clicks, Booster Packs, Props... you could have a cross-compatible platform? Something that doesn't force you into one chipset? and allows you to mix-and-match the microcontroller, wireless protocol, and functional extensions?

Yeah, me too! That's why I created Feather. Feather is a flexible and powerful family of microcontroller main-boards (Feathers) and daughter-boards (Wings) with a wide range of capabilities.

Feathers!

Since we aren't tied to one chip manufacturer, we feature the best-of-the-market chipsets, including:

  • Atmel ATmega32u4 - 8 bit AVR
  • Atmel ATSAMD21 - 32 bit ARM Cortex M0+
  • Broadcom/Cypress WICED - STM32 with WiFi
  • Espressif ESP8266 and ESP32 - Tensilica with WiFi/BT
  • Freescale MK20 - ARM Cortex M4, as the Teensy 3.2 Feather Adapter
  • Nordic nRF51 and nRF52 - ARM Cortex & Bluetooth LE
  • Packet radio modules featuring SemTech SX1231
  • LoRa radio modules featuring SemTech SX127x

and many more to come!

Wings!

Once you've picked your main dish (the Feather mainboard) you can pick and choose from a wide wide variety of Wings. Wings are like little "shields" or "HATs" for Feathers. You can (in theory) add as many Wings as you like to a single Feather main-board, as long as you don't run out of power, space or have pin collisions.

Best of all, we've tested all of our Wings against all of our Feathers. So, other than a few exceptions (mostly the GPS Featherwing), you can re-use, re-cycle, and upgrade your Feathers and Wings between projects and as need arises.

For example, start out with a Feather 32u4, then decide to upgrade to the Feather M0 for more Flash - the pin out is the same! Or, make an IoT project with the ESP8266 and then super-power it with an ESP32 just by swapping out the main Feather. Maybe build a project with a Feather M0 Bluefruit, then realize you need more range so you switch to a Feather M0 LoRa.

The Feathers and Wings all have example code written in Arduino C/C++ so as your projects adapt, all your wings and code will come along with you.
