Qwiic, or STEMMA QT, is a very efficient way to quickly prototype an idea, but a lot of Qwiic/Stemma QT driver boards only have one port, and devices have...

The datasheet for the DS3231 explains that this part is an "Extremely Accurate I²C-Integrated RTC/TCXO/Crystal". And, hey, it does exactly what it says on the tin! This Real Time Clock (RTC) is the most precise you can get in a small, low-power package.

Most low cost soil sensors are resistive style, where there's two prongs and the sensor measures the conductivity between the two. These work OK at first, but eventually...

Solenoids are a little like cats: if your project has one solenoid you'll probably stick with just one and in such cases our single MOSFET driver will...

We got a request from a customer for a board that makes connecting between a breadboard and Stemma QT or Qwiic components easy, and here's what we...

Expand your project possibilities, with the Adafruit AW9523 GPIO Expander and LED Driver Breakout - a cute and powerful I2C expander with a lot of tricks up it's sleeve.

Add high quality motion, direction and orientation sensing to your Arduino project with this all-in-one 9 Degree of Freedom (9-DoF) sensor with sensors from ST...

This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for data-logging, clock-building, time stamping, timers, and alarms, etc. Equipped with PCF8523 RTC - it can run from 3.3V or 5V power & logic!

Sensirion Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. And finally, Adafruit have some that have a true I2C interface for easy reading. The SHTC3 sensor has an excellent ±2% relative humidity and ±0.2 °C accuracy for most uses. Unlike some earlier SHT sensors, this sensor has a true I2C interface on address 0x70.

NeoPixel LEDs (a.k.a WS2812 / SK6812 family) are a super-easy way to add addressable RGB lighting with only one GPIO. They're ubiquitous on...

The ANO rotary encoder wheel is a funky user interface element, reminiscent of the original clicking scroll wheel interface on the first iPods. It's a...

This is a STEMMA I2C breakout for the Infineon OPTIGA TRUST M SLS 32AIA. OPTIGA Trust M is the next generation of Trust X. OPTIGA Trust M brings RSA 1K/2K + ECC256/384.

Now you can quickly integrate the Sensirion SEN6x environmental sensor node into your microcontroller or microcomputer project, with no soldering or...

The Adafruit VL53L4CX Time of Flight Sensor is another great Time of Flight distance sensor from ST in the VL5 series of chips, this one is great for long...

If you're looking to use the Qwiic / Stemma QT standard for your next project - but you're using a sensor or device that requires 5V power or...

This breakout board is a "three in one" product:The ATtiny817 is part of the 'next gen' of AVR microcontrollers, and now we have a cute...

This OLED goes out to all the fans who want more pixels in a smaller size! Normally our 128x64 OLEDs are the biggest ones we've stocked that can use...

Bedeck your Feather project with a beautiful Adafruit TFT FeatherWing, 3.5" 480x320 Capacitive Touchscreen. This TFT display is 3.5" diagonal...

Here is the perfect hardware kit to make a RP2040 QT Trinkey into any kind of USB-connected smart sensor with a QT-sensor-sandwich! You can assemble...

Back in my day, we used to have these big chunky PC joysticks that would plug into the back of your PC. No, not through USB, they had a DE-15 port and...
