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 ...

Sometimes you need to sense pressure in a damp environment. And sometimes you need to know the relative changes in pressure as well as the absol...

I2C stands for Inter-Integrated-Circuit communications, its meant for short distances on a PCB or subassembly. But, hey, we're engineers and we ...

The Adafruit LTR-303 Light Sensor a simple and popular low-cost I2C digital light sensor that is easy to integrate into your project for reliable a...

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 with STEMMA QT ...

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The Adafruit MCP9600 does all that for you, and ca...

This miniature GPS breakout is only 1" x 1" (~ 25mm x 25mm) but houses a complete GPS/GNSS solution with both I2C and UART interfaces. There's even...

Make a game or robotic controller for any I2C microcontroller or microcomputer with this tiny gamepad breakout board. This design has a 2-axis thum...

The MSA311 is a super small and low-cost triple-axis accelerometer. It's inexpensive, but has just about every 'extra' you'd want in an acceleromet...

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 microco...

Our family of I2C-friendly user interface elements grows by one with this new product that makes it plug-n-play-easy to add a 75mm long slide poten...

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 ...

You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize "Uh oh, this chip has ...

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 four of ...

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, ...
