LCD1602 I2C Module, White color with blue background, 16x2 characters LCD, 3.3V/5V...

Read (and write) RFID/NFC tags with this compact module.

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...

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...

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...

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...

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...

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

The DS1307 Real Time Clock developed by one of our designers: Waiman. The module comes fully assembled and pre-programmed with the current time (ok, so it's our current time - MST).

Play simple tones or even melodies - add an audible alert to your project.

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...

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...

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...

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!

Expand your project possibilities, with the Adafruit PCF8574 GPIO Expander Breakout - an affordable 8 channel I2C expander.GPIO expanders work like this:...

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...

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 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...

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...

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

A 16-bit self-calibrating analog-to-digital converter that operates on I2C

If you're a person like me that gets exhausted turning knobs all day, the DS3502 is just the ticket to calm all your knob-turning related troubles. Instead of having...
