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...

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...

ESP32-S3 Microcontroller with headers, 2.4 GHz Wi-Fi Development Board, dual-core processor with frequency up to 240 MHz…

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...

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...

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...

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...

The SparkFun Qwiic Adapter provides the perfect means to make any old I2C board into a Qwiic-enabled board. This adapter breaks out the I2C pins from the Qwiic connectors...

This is an I2C DAC module that outputs 0-25mA current. It offers more accurate 4-20mA current output after calibration, which can be used with most 4-20mA...

USB To UART/I2C/SPI/JTAG Converter, Supports Multiple Interfaces, Compatible with 3.3V and 5V, Multiple Protection Circuits, Multiple Systems Support,...

On the same I2C port, DFRobot Gravity: I2C Multiplexer solves the address conflict and enables the normal communication with multiple same-address I2C devices. You...

Cooling fans...They're everywhere, and they serve the important purpose of keeping things cool, generally electronics. One might rightfully think: "these fans are pretty good at moving air to keep things cool; maybe I can use one of these neat computer fans to keep my widget frosty" followed closely by throwing up one's hands in confusion at the sight of a 3 or even 4-pin connector. OK, power takes two pins but what are these other pins for and how do I use them to convince this fan to keep my things chilly?

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

The SparkFun Qwiic ISM330DHCX 6DoF IMU is a standard-sized, 1"x1" breakout featuring a high-performance 3D digital accelerometer and 3D digital gyroscope...

Add another 16 pins to your microcontroller using a MCP23017 port expander. The MCP23017 uses two i2c pins (these can be shared with other i2c devices), and in exchange...

Add another 8 pins to your microcontroller using a MCP23008 port expander. The MCP23008 uses two i2c pins (these can be shared with other i2c devices), and in exchange...

This module enables galvanically isolated bidirectional I²C communication between two devices while supplying regulated, isolated power to the target. The...

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.

You want to make a cool Arduino 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...

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 detents for tactile feedback. But, if you've ever tried to add encoders to your project you know that they're a real challenge to use: timers, interrupts, debouncing...

High-resolution, high-precision, dual-channel DAC voltage module. Expandable to 16 output channels through I2C cascading...

The SparkFun Pulse Oximeter and Heart Rate Sensor is an I2C based biometric sensor, utilizing two chips from Maxim Integrated: the MAX32664 Biometric Sensor Hub...

We're glad to introduce a new member in Gravity family: Gravity I2C SD2405 RTC module. This is an extremely accurate I2C real-time clock (RTC) with crystal compensation...

This module enables galvanically isolated bidirectional I²C communication between two devices while supplying regulated, isolated power to the target. The...

The DHT20 is a nice but inexpensive temperature and humidity sensor from the same folks that brought us the DHT22.This little sensor looks an awful...
