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 a fixed I2C address...

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...

You want to make a cool robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise...

You’ve always wanted to output analog voltages from a microcontroller, the MCP4725 is the DAC that will let you do it! The MCP4725 is an I2C controlled Digital-to-Analog converter (DAC). A DAC allows you to send analog signal, such as a sine wave, from a digital source, such as the I2C interface on the Arduino microcontroller. Digital to analog converters are great for sound generation, musical instruments, and many other creative projects!

Do you have too many sensors with the same I2C address? Put them on the SparkFun Qwiic Mux Breakout to get them all talking on the same bus! The Qwiic Mux Breakout...

Add a colourful light-up dial and turn your Raspberry Pi project up to 11!

Oh boy, this is a Big. Damn. Switch. Program it to switch loads up to 40V / 10A connected to the HT0740 breakout's sturdy screw terminals, and use up to...

Add oodles of extra analog-friendly input and output pins to your Raspberry Pi project!

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...

Wouldn't it be cool to drive a tiny OLED display, read a color sensor, or even just flash some LEDs directly from your computer? Sure you can program an Arduino...

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 them to...

FRAM, or Ferroelectric Ram, is the coolest new data storage method that all the fashion magazines are talking about. Oh wait, no that's quilted handbags. But FRAM...

I2C stands for Inter-Integrated-Circuit communications, its meant for short distances on a PCB or subassembly. But, hey, Adafruit are engineers and Adafruit like to push the limits of technology, right? So why not try to have I2C run over a meter long cable, or even longer?

By customer request, this is a DS2484 Stemma QT board that uses a I2C-to-1W controller chip, with ESD protection and support for split supplies. You can...

Add lots of touch sensors to your next microcontroller project with this easy-to-use 8-channel capacitive touch sensor breakout board, starring the CAP1188. This...

If you want to store calibration values, MAC addresses, non-secure access tokens, or other unique identifiers, EEPROM storage is a great option. EEPROM is long lasting, and doesn't need to be written in pages - a single byte can be written at once (unlike with flash memory!) EEPROM storage persists even when the power goes out, and can be over-written literally one million times.

This RFID tag is really unique: it works with mobile phones just like other RFID tags, but you can reprogram it over I2C!

If you've ever said to yourself, "Gee, I wish I had eight 10-bit DACs that came in a single package", well I have good news. The Adafruit...

Analog Devices, known for their reliable and well-documented sensor chips - has a high precision and high resolution temperature sensor on the market, and Adafruit have...

Potentiometers are the perfect tool when you want to change your circuit by turning a knob. Turns out, there are times when you want to adjust your circuit without manually turning a knob, and the DS1841 I2C Logarithmic Resistor from Maxim can do just that. It's a programmable resistor, similar to an I2C potentiometer like the DS3502 I2C Potentiometer, so why another?

The MCP9808 digital temperature sensor is one of the more accurate/precise we've ever seen, with a typical accuracy of ±0.25°C over the sensor's -40°C to +125°C range and precision of +0.0625°C. They work great with any microcontroller using standard I2C. With three address jumpers on the back, you can connect up to 8 to a single I2C bus without address collisions. Best of all, a wide voltage range makes it usable with 2.7V to 5.5V logic!

This new Adafruit shield makes it easy to use a 16x2 Character LCD. The 16x2 Character LCD is NOT, repeat, NOT, included Adafruit really like the range of LCDs Adafruit stock...
