The Adafruit 5x5 NeoPixel Grid BFF can attach to the back of a QT Py or Xiao board. Onboard is a grid of 25 1.5x1.5mm NeoPixel LEDs connected to pin A3 by default. You can cut/solder some jumpers to select A1, or A2 instead if you like. There's also solder pads for 5V, GND and IN data, in case you want to power externally.

The Adafruit NeoPixel Driver BFF lets you quickly add a strand of NeoPixels with a 5V level shifter and a detachable JST PH connector. This PCB is designed to fit onto the back of any QT Py or Xiao board with headers or by soldering directly. Onboard is a 74AHCT125 single-gate level shifter that will take pin A3 output and shift it up to 5V using the USB power as a reference.

To make prototyping and designing with QSPI flash a little easier, we designed these breakouts that convert the wide 8-SOIC packages to a cute 0.3" wide DIP. They're available with 16Mbit, 64Mbit and 128Mbit size chips. We find these handy when testing out different flash sizes, or if we just want to add more storage memory to a project.

If you just need a megabyte or two of extra storage for a project, we recommend an Adafruit SPI FLASH Breakout. The breakout is single-channel SPI only, but it comes with level shifting so it can be used safely with 3V or 5V power and logic. You can address them as a flat memory space or, if you like, format them with a filesystem like littleFS or FAT.

This board is like a little ray gun for infrared light, with two high powered LED outputs. When controlled with the onboard N-Channel FET driver, you'll be blasting 100mA-200mA of current pulsing through each LED for 10+ meters of range! This is the easiest way to get great IR emitter range without wiring up a bunch of parts.

You can setup an HTTP server with a Pico W running CircuitPython. This example sets a static IP address for the server, logs temperature readings from a DS18B20 temperature sensor, displays server information on an OLED and serves an HTML webpage with buttons that can send HTTP POST requests to toggle pins on the Pico W.

This project gets you from zero to flapping vampire bat with no soldering required. Two servo motors attach to the Circuit Playground Express with alligator clips. The NeoPixels on the Circuit Playground Express swirl around with a fun animation.

Utilize the CLUE onboard BMP280 sensor to measure ambient temperature and air pressure. A servo position moves depending on your nominal baseline pressure compared to the air pressure reading to point to the current weather condition. You'll use the PyLeap app will wirelessly load the project onto your CLUE over Bluetooth and then edit your nominal baseline pressure with the File Glider app.

The PCA9548 gives you a way to get up to 8 same-address I2C devices hooked up to one microcontroller - this multiplexer acts as a gatekeeper, shuttling the commands to the selected I2C port with your command.

Raspberry Pi Pico W brings WiFi to the Pico platform while retaining complete pin compatibility with its older sibling, and now as of CircuitPython 8.0.0-beta.2, there is CircuitPython WiFi support for the Pico W! This guide includes examples for testing your WiFi connection, using requests to pull JSON feeds, ping API's and log sensor data for IoT projects; all using CircuitPython!

Turn your CLUE into a custom conference badge to display your online handle, name, job title and pronouns. You'll be able to edit your badge's details using the File Glider app.

In this project, you'll use the PyLeap app to wirelessly load the project code onto your CLUE. Then, you'll connect to the CLUE with the Adafruit Bluefruit Connect app to change the colors and animations of a strip of NeoPixels over BLE.

In this project, you'll build a custom 3D printed trombone controller for the game Trombone Champ. A QT Py RP2040 running CircuitPython code uses an arcade button and NeoSlider to control the game. The button sends a space bar command the NeoSlider moves the mouse cursor up and down.

You can build a digital nose with the ENS160 Gas Sensor, a fully integrated MOX gas sensor. This is a very fine air quality sensor from the sensor experts at ScioSense, with I2C interfacing so you don't have to manage the heater and analog reading of a MOX sensor. It combines multiple metal-oxide sensing and heating elements on one chip to provide more detailed air quality signals.

The CLUE has tons of onboard sensors that can sense movement, light, sound and environmental measures like temperature and humidity. This project uploads code to the CLUE with PyLeap that uses the CLUE's onboard display to plot all of the sensors' data.
