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...

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...

Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to...

The HUSB238 USB PD sink chip is neat in that you can either use switches (really, resistor selection) to set the desired PD voltage or use I2C for dynamic...

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?

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?

We launched the Serial CAN Bus Module years ago, which is very practical and easy to use. Now we have slightly modified the Serial CAN Bus...

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

The ANO rotary encoder wheel is a funky user interface element, reminiscent of the original clicking scroll wheel interface on the first iPods. It's a...

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...

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...

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

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...

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

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...

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.

This board is an integrated solution for monitoring voltage, current, power, and other parameters in AC and DC systems featuring Allegro’s...

I2C Breakout shield for the TinyPICO & TinyS2...

This USB-to-I²C adapter enables a PC or other USB host to act as the controller on an I²C bus, reading and writing data from I²C target devices connected...

The RP2040 Interfacer is a small low-cost USB to UART and I2C Adapter (both 3.3V) powered by an RP2040 microcontroller that plugs straight into a USB Type-A...

The only thing better than a nice mechanical key is, perhaps, FOUR mechanical keys that also can glow any color of the rainbow - and that's what the Adafruit NeoKey 1x4 QT I2C Breakout will let you do! This longgg 3" x 0.8" PCB fits four Cherry MX or compatible switches and make it easy to use with a breadboard/perfboard or with a STEMMA QT (Qwiic) connector for instant I2C connectivity on any platform.

The SparkFun Navigation Switch adds a small, joystick-like 5-way tactile switch to your I2C bus! When connected to a microcontroller, push the 5-way...

This module enables galvanically isolated bidirectional I²C communication between two devices. The bidirectionality applies to both SDA and SCL, which...

Analog switches are a solid state alternative to relays, when you want a smaller, lower-power technology that won't wear out mechanically. And, as the...
