You just found the perfect I2C sensor, available in a handy chainable Qwiic, or STEMMA QT package, and you want to wire up two or three or more of them to...

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.

If you've ever said to yourself, "Gee, I wish I had four 12-bit DACs that came in a single package with the ability to save their settings to an EEPROM", well I...

Expand your project possibilities, with the Adafruit PCF8574 GPIO Expander Breakout - an affordable 8 channel I2C expander.GPIO expanders work like this:...

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 the BH1750 16-bit Ambient Light Sensor from Rohm. Because of how important it is to humans and most other living things, sensing the amount of light in an environment is a common place to get started when learning to work with microcontrollers and sensors.

These displays are small, only about 1.3" diagonal, but very readable due to the high contrast of an OLED display. This display is made of 128x64 individual white...

It's half USB Key, half Adafruit QT Py, and a lotta RP2040...it's Trinkey QT2040, the circuit board with an RP2040 heart and Stemma QT legs. Folks are loving the QT Py 2040 we made, but maybe you want something plug-and-play. So we thought, hey what if we made something like that plugs right into your computer's USB port? And this is what we came up with!

Do you find yourself wishing that you had just a few more GPIO pins? What if you only need that one more pin? You could add another microcontroller to your project...

The ESP32-S3 has arrived in Feather format - and what a great way to get started with this powerful new chip from Espressif! With dual 240 MHz cores, WiFi...

Now you can quickly integrate the Sensirion SEN54 / SEN55 environmental sensor node into your microcontroller or microcomputer project, with no soldering...

At SparkFun we continually like to inovate, update, and improve even when it comes to our very own development boards. We have multiple versions of the SparkFun...

Add motion, direction and orientation sensing to your project with this all-in-one 9-DOF sensor that is STEMMA QT ready for easy plug-n-play usage. 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.

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...

Most accelerometers have a similar range of measurements that they can make: often around 2G - 16G. Similarly, most gyros can measure in the range of 250 degree/s...
