This compact IoT board features a dual-core 240 MHz processor, 2.4 GHz WiFi, and Bluetooth LE. The w.FL antenna connector allows for an external antenna, increasing range and stability. The board offers 8 MB of Flash, 512 KB of SRAM, native USB with HID and MIDI support, and a built-in LiPo charger with a MAX17048 battery monitor. It also includes a STEMMA QT connector, a programmable NeoPixel, and full compatibility with the Feather ecosystem. The Adafruit 5885

The Qwiic connector overlay provides an easy-to-install way to add Qwiic connectors to Thing Plus and Feather boards. Communication takes place via the I2C interface. Sparkfun DEV-16790

FeatherWing Proto - Prototyping Add-on For All Feather Boards

Pin expander designed for Feather plates. It is equipped with three sets of female strips and holes for prototyping. Adafruit 3417

Development board with ESP8266 microcontroller with built-in Wi-Fi communication. The system is clocked at 80 MHz and powered by 3.3 V. It includes a Tensillica core and a full Wi-Fi stack. Adafruit 3046

Adafruit Feather M0 Express - Designed for CircuitPython is a development board with a 32-bit ATSAMD21G18 microcontroller based on the Cortex-M0 core. The board works with CircuitPython, which allows you to program the MicroPython language. Adafruit 3403

Bluetooth Low Energy, 2.4GHz spectrum wireless protocol. Excellent for use in portable projects that will make use of an iOS or Android phone or tablet. It also is supported in Mac OS X and Windows 8+. Adafruit 2829

Cap for use with shallow Feather series, with radio module RFM95W 900MHz. It offers a range of up to 2 kilometers (the range can be increased by using an external antenna). It has a SPI interface. Adafruit 3231

Adafruit Feather 328P is a module with a built-in ATmega 328P AVR microcontroller (8MHz, 32kB Flash, 2kB RAM). The board is compatible with Arduino IDE, has small dimensions and low weight, and the built-in USB connector allows programming and debugging. Adafruit 3458

Module with a matrix LED RGB 6x12 display (72 LEDs) designed to work with Feather plates. It communicates via a two-wire SPI interface. Adafruit 3449

At the Feather M0\'s heart is an ATSAMD21G18 ARM Cortex M0 processor, clocked at 48 MHz and at 3.3V logic, the same one used in the new Arduino Zero. This chip has a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much)! This chip comes with built in USB so it has USB-to-Serial program & debug capability built in with no need for an FTDI-like chip. Adafruit 3179

Development board with Renesas RA6M5 microcontroller, running at 200 MHz with built-in Flash memory and easy sensor connection thanks to Feather form factor and Qwiic connector. Equipped with Bluetooth Low Energy connectivity and SmartBond technology - CodeLess AT command Datapump, the board allows easy configuration without the need for reprogramming, making it suitable for both beginners and advanced users. SparkFun WRL-24243

At the Feather 32u4\'s heart is ATmega32u4 clocked at 8 MHz and at 3.3V logic. 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. Adafruit 2795

This module enables the Feather series range to be expanded with 8 12-bit PWM outputs that can be used, for example, to control servos or LED diodes. Adafruit 2928

These add-ons for any Feather board will let you integrate packetized radio (with the RFM69 radio) or LoRa radio (with the RFM9x\'s). These radios are good options for kilometer-range radio, and paired with one of our WiFi, cellular or Bluetooth Feathers, will let you bridge from 433/900 MHz to the Internet or your mobile device. Adafruit 3232

This is the FeatherWing OLED: it adds a 128x32 monochrome OLED plus 3 user buttons to any Feather main board. Using our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top of your Feather board and let the board take flight. Adafruit 2900
