Sometimes you'll find yourself with an I2C bus controller on one side, and an I2C bus device on the other and you gotta keep em (electrically) separated. Maybe because one is Earth-grounded, maybe because you've got some funky power monitoring setup, maybe you want to reduce noise.

This 4-wire cable is 50mm / 1.9" long and fitted with JST SH female 4-pin connectors on both ends. Compared with the chunkier JST PH these are 1mm pitch instead...

This cable will make it super easy to use our plug-and-play STEMMA QT boards and controllers with chips, breakouts, and other devices that are I2C compatible but don't come with a STEMMA QT socket already on 'em.

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...

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...

Rotary encoders are soooo much fun! Twist em this way, then twist them that way. Unlike potentiometers, they go all the way around and often have little...

We’ve gotten a lot of requests for a MCP23017 breakout and we’ve always sorta been like “ehh why not just use the DIP chip?” but...

The ScoutMakes FM Radio Board is a great way to learn about the world of electronics. It is an I2C breakout board for the RDA5807 FM radio chip by RDA...

Take a deep breath in...now slowly breathe out. Mmm isn't it wonderful? All that air around us, which we bring into our lungs, extracts oxygen from, and then breathe out carbon dioxide. CO2 is essential for life on this planet we call Earth - we and plants take turns using and emitting CO2 in an elegant symbiosis. But it's important to keep that CO2 balanced - you don't want too much around, not good for humans and not good for our planet.

This 4-wire cable is a little over 400mm / 15.7" long and fitted with JST-SH female 4-pin connectors on both ends. Compared with the chunkier JST-PH...

It’s not hard to find an accelerometer that can measure accelerations up to 16g, but if you need an accelerometer that can measure even larger amounts of acceleration, your options narrow.

The only thing better than a glowy arcade button is, perhaps, FOUR glowing arcade buttons - and that's what the Adafruit LED Arcade Button 1x4 QT...

Bosch has been a leader in barometric pressure sensors, from the BMP085. BMP180, BMP280, BMP388... now Adafruit have got the next generation, the Adafruit BMP390 Precision Barometric Pressure and Altimeter Breakout. As you would expect, this sensor is similar to its earlier versions but even better. The BMP390 has better precision than ever, which makes it excellent for environmental sensing or as a precision altimeter. It can even be used in either I2C and SPI configurations.

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

Do you know which way the wind blows? You will now, with this triple-axis accelerometer/magnetometer compass module. Inside are two sensors, one is a classic 3-axis...

Behold, the ST LSM6DSO32: The latest in a long line of quality Accelerometer+Gyroscope 6-DOF IMUs from ST. This lil IMU is like a big sister to the LSM6DSOX, it has the same pin out and firmware - but the accelerometer component can go up to 32g instead of the normal 16g maximum.

The Adafruit TCA4307 Hot-Swap I2C Buffer breakout here solves that problem. It's specifically designed to take a non-hot-swap protocol (I2C) and protect the controller from wayward peripherals messing with the bus during attach/detach.

*sniff* *sniff* ... do you smell that? No need to stick your nose into a carton of milk anymore, you can build a digital nose with the SGP40 Multi-Pixel Gas Sensor, a fully integrated MOX gas sensor. This is a very fine air quality sensor from the sensor experts at Sensirion, 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.

Dig out that old Wii controller and use it as a sleek controller for your next robot if you like. The Adafruit Adafruit Wii Nunchuck Breakout Adapter fits snugly into the Wii connector, and performs the level shifting and power regulation needed to use the controller with any microcontroller or microcomputer.

The HTU31-D is the third generation of temperature-humidity sensors from TE - and a great follow-up to the popular HTU21-D sensor. Like the HTU21, the '31 is great for sensing temperature and humidity, with excellent specifications.

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.

We live on a planet with an atmosphere, a big ocean of gaseous air that keeps everything alive - and that atmosphere is constantly bouncing off of us, exerting air...

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...

If you've ever ordered and wire up a 9-DOF sensor, chances are you've also realized the challenge of turning the sensor data from an accelerometer, gyroscope, and magnetometer into actual "3D space orientation"! Orientation is a hard problem to solve. The sensor fusion algorithms (the secret sauce that blends accelerometer, magnetometer, and gyroscope data into stable three-axis orientation output) can be mind-numbingly difficult to get right and implement on low-cost real-time systems.

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...
