Adafruit LSM9DS1 Accelerometer + Gyro + Magnetometer 9-DOF Breakout

Sooo Maaaany DooooooFs!

Add motion, direction and orientation sensing to your Arduino project with this all-in-one 9-DOF sensor. Inside the chip are three sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gravity) or how fast the board is accelerating in 3D space. The other is a 3-axis magnetometer that can sense where the strongest magnetic force is coming from, generally used to detect magnetic north. The third is a 3-axis gyroscope that can measure spin and twist. By combining this data you can REALLY orient yourself.

Adafruit Music Maker FeatherWing

Bumpin' tooonz for your Feather board

Bend all audio files to your will with the Adafruit Music Maker FeatherWing! It's a fun-size version of our Music Maker shield for Arduino! This powerful 'Wing features the VS1053, a chip that can decode a wide variety of audio formats such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV (PCM and ADPCM).

Adafruit Speaker Bonnet for Raspberry Pi

Turn it up!

This Bonnet uses I2S a digital sound standard, so you get really crisp audio. The digital data goes right into the amplifier so there's no static like you hear from the headphone jack. And it's super easy to get started. Just plug in any 4 to 8 ohm speakers, up to 3 Watts, run our installer script on any Raspberry Pi, reboot and you're ready to jam!

Adafruit VL6180X Time of Flight Micro-LIDAR Distance Sensor Breakout

Bounce a mini laser off stuff!

The VL6180X is a Time of Flight distance sensor like no other you've used! The sensor contains a very tiny invisible laser source, and a matching sensor. The VL6180X can detect the "time of flight", or how long the light has taken to bounce back to the sensor. Since it uses a very narrow light source, it is good for determining distance of only the surface directly in front of it. Unlike sonars that bounce ultrasonic waves, the 'cone' of sensing is very narrow. Unlike IR distance sensors that try to measure the amount of light bounced, the VL6180X is much more precise and doesn't have linearity problems or 'double imaging' where you can't tell if an object is very far or very close.

Timelapse Spy Camera

Create a battery powered timelapse camera!

Using a Spycam, Trinket & Lipo make a tiny & portable timelapse device!

Easy Alexa (Echo) Control of your ESP8266 Huzzah

"Alexa, do something cool with my 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!

Adafruit VL53L0X Time of Flight Micro-LIDAR Distance Sensor Breakout

Use the power of photons for good!

The VL53L0X is a Time of Flight distance sensor like no other you've used! The sensor contains a very tiny invisible laser source, and a matching sensor. The VL53L0X can detect the "time of flight", or how long the light has taken to bounce back to the sensor. Since it uses a very narrow light source, it is good for determining distance of only the surface directly in front of it. Unlike sonars that bounce ultrasonic waves, the 'cone' of sensing is very narrow. Unlike IR distance sensors that try to measure the amount of light bounced, the VL53L0x is much more precise and doesn't have linearity problems or 'double imaging' where you can't tell if an object is very far or very close.

Adafruit MAX31865 RTD PT100 Amplifier

PT100 Cruisin'

To get precision and accuracy out of your PT100 RTD you must use an amplifier that is designed to read the low resistance. Better yet, have an amplifier that can automatically adjust and compensate for the resistance of the connecting wires. If you're looking for a great RTD sensor, today is your lucky day because we have a lovely Adafruit RTD Sensor Amplifier with the MAX31865 breakout for use with any 2, 3 or 4 wire PT100 RTD!

Adafruit 2.4" TFT FeatherWing

A lovely color display for any Feather, show off your Feather plumage!

Spice up your Feather project with a beautiful 2.4" touchscreen display shield with built in microSD card socket. This TFT display is 2.4" diagonal with a bright 4 white-LED backlight. You get 240x320 pixels with individual 16-bit color pixel control. It has way more resolution than a black and white 128x64 display. As a bonus, this display comes with a resistive touchscreen attached to it already, so you can detect finger presses anywhere on

Adafruit DRV8833 DC/Stepper Motor Driver Breakout Board

Chopper it up with current limiting motor control

Spin two DC motors or step one bi-polar or uni-polar stepper with up to 1.2A per channel using the DRV8833. This motor driver chip is a nice alternative to the TB6612 driver. Like that chip, you get 2 full H-bridges, but this chip is better for low voltage uses (can run from 2.7V up to 10.8V motor power) and has built in current limiting capability. We set it up for 1A current limiting so you don't get more than 2A per chip, but you can also disable the current limiting, or change it to a different limit!

Adafruit MAX31856 Universal Thermocouple Amplifier

Now you can handle any kind of thermocouple!

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference, as well as calculations to handle any non-linearities. For a long time we've suggested our MAX31855K breakout, which works great but is only for K-type thermocouples. Now we're happy to offer a great new thermocouple amplifier/converter that can handle just about any type of thermocouple, and even has the ability to give you notification when the temperature goes out of range, or a fault occurs. Very fancy! This converter communicates over 4-wire SPI and can interface with any K, J, N, R, S, T, E, or B type thermocouple

Adafruit Si7021 Temperature + Humidity Sensor

Get the current ambient temperature and humidity

This lovely sensor for Silicon labs has ± 3% relative humidity measurements with a range of 0–80% RH, and ±0.4 °C temperature accuracy at a range of -10 to +85 °C. Great for all of your environmental sensing projects. It uses I2C for data transfer so it works with a wide range of microcontrollers.
