Adafruit Feather 328P

Classic ATmega328p tech with the new modern Feathers

With this Feather we're getting a little nostalgic for the ATmega328P - the classic 'Arduino' chip - with this Adafruit Feather 328P running a 3.3V and 8 MHz. Feather is the new development board from Adafruit, and like it's namesake it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores.

Adafruit nRF52 Pro Feather with Mynewt

Take your Bluetooth LE projects to the next level with the mynewt RTOS

The Adafruit Feather nRF52 Pro ships pre-programmed with the Mynewt serial bootloader that allows you to flash firmware to the device directly from the command-line using the on-board USB Serial converter and the 'newtmgr' tool, so you can get started right away with no additional hardware required. For more advanced debugging, however, you can use a Segger J-Link and the on-board SWD debug connector, which gives you access to a more powerful set of development tools and options.

Introducing Adafruit Feather

Boards of a Feather flock together!

Welcome to the Wonderful World of Feathers! This guide will tell you all about the dozens of options you have to build your next Feather project.

Adafruit HUZZAH32 - ESP32 Feather

WiFi, Bluetooth, peripherals galore!

Aww yeah, it's the Feather you have been waiting for! The HUZZAH32 is our ESP32-based Feather, made with the official WROOM32 module. We packed everything you love about Feathers: built in USB-to-Serial converter, automatic bootloader reset, Lithium Ion/Polymer charger, and all the GPIO brought out so you can use it with any of our Feather Wings.

Remote Effects Trigger Box

Build this powerful RF Feather-based controller to wirelessly trigger props, lights, effects, and more!

Using 900Mhz (or 425Mhz) RF for long-range communications between the transmitter and the receivers, this general purpose controller will make your wireless triggering wishes come true! Plus, you get to use a rotary encoder knob to scroll menu sets, and punch in your commands on the lighted 4x4 Trellis keypad.

Coffee Detonator: The TNT Plunger Grinder

Use a high-voltage AC power source to trigger a Feather microcontroller-driven coffee grinder.

This guide will show you how a magneto, generator, or other AC power source can be safely converted into a small DC signal easily read by an Arduino-compatible microcontroller. Then, the microcontroller can trigger a 120V relay to turn on any appliance!

Adafruit Feather M0 Express - Designed for CircuitPython

Get running faster than ever with the first Adafruit Express board

Get started quickly using Arduino or CircuitPython on the Feather M0 Express.

Magic Wand

A Magic Wand responds to movement to cast spells

This project turns a toy hammer into a magic wand that produces different sound and light effects depending on the spell cast based on simple gesture recognition. The amount of components in this project combined with the small room requires a bit of cramfu to get all the parts to fit. The compact nature of this project and the number of components means it's a best for a somewhat experienced maker.

Bluefruit nRF52 Feather Learning Guide

Get started now with our most powerful Bluefruit board yet!

by Kevin Townsend

This learning guide will help you get setup and started with the ARM Cortex M4F based nRF52 Bluetooth Low Energy system on chip. You can run your Arduino code directly on the nRF52, and take advantage of the SoC's high performance, without sacrificing ease of use.

Level Shifting 3.3V microcontrollers and NeoPixels

Level shifters are like little bilingual translators for your electronics!

NeoPixels rule! But, they expect 5V logic, which can cause them to act funny when controlled by 3v3 boards, such as Feathers, M0-based Arduinos, Teensy 3, and others. Not to worry! A level shifter can translate 3v3 logic to 5V and get things talking again in no time!

Using Bluefruit BLE to Give Disabled Users Switch Control Access to IOS Devices

Build an inexpensive Bluetooth device to give a disable user access to their iPad or iPhone

A physical disability can make it impossible to operate a touchscreen device such as an iPhone or iPad. Commercially available switch control devices can cost several hundred dollars but with the power of Adafruit Bluefruit BLE devices you can build an interface for a fraction of that cost. We show you how in this tutorial.

Kombucha Thermostat with CircuitPython and Feather

You can easily adapt the code to add any number of devices to a single Feather for all sorts of interactive home automation projects with ease!

Schluff - The Sleep Monitor

Find the ideal conditions for a good nights rest

by Michael Sklar

Schluff is a Yiddish word which means to take a short nap. This project is about finding the ideal environment for quality sleep by monitoring different conditions and biometric data. Ideally, the data from this device would be overlayed with a wrist-based fitness tracker for additional revelations. Schluff records the following: temperature, humidity, light, noise and heart rate. The collected data is sent from a Feather 32u4 (Arduino compatible) over to an iOS device or macOS laptop using BLE (Bluetooth Low Energy). The BLE catchers can save the data locally or relay it up to adafruit.io for storage and graphing.

MAC Address Finder

Quickly find the MAC address on devices where doing so isn't so easy.

In most situations finding the MAC address of a wireless device is fairly straightforward. However, there are some things like smart TVs, IOT devices, gaming consoles, etc. that either don't display that MAC or have it hidden in a mess of on-screen menus. This device broadcasts a wireless network without a password. Connect any wireless device to it and once the connection is made the MAC address of the device will be displayed on the small OLED screen.
