PWM signal-driven, easy and convenient. Single-channel 0-10V industrial voltage DAC module. Used for automation scenarios like lighting adjustment,...

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...

The INA228 is an amazing power monitoring chip, with best-of-everything support: up to 85VDC common-mode, high or low side measurements, 20-bit (!) ADC...

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...

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...

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...

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?

Gravity: UART & I2C NFC Module adopts NXP PN532, a highly integrated NFC communication controller, which supports various types of NFC smart cards or tags like the commonly used MIFARE Classic series and NTAG series in the market

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...

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...

The Servo PWM Pi is a 16-channel, 12-bit PWM controller for the Raspberry Pi, suitable for driving LEDs and radio control servos. The board is based around PCA9685 PWM I2C LED controller IC from NXT and can drive each of the 16 outputs with 12 bit (4096 steps) duty cycle from 0% to 100%.

This CH423 IO expansion board extends 24 digital ports via I2C, including 8 GPIOs with interrupt functions and 16 GPOs...

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

Easily change I2C sensor addresses with DFRobot’s plug-and-play I2C address shifter. Fix I2C conflicts, support multiple sensors, and simplify wiring....

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

This I2C button module with RGB LED not only supports reading button status like conventional ones, but also controlling RGB LED color and switching...

DFRobot Gravity 12-Bit I2C DAC is a small and easy-to-use 12-bit digital-to-analog converter with EEPROM. It can accurately convert the digital value to corresponding...

High-resolution, high-precision single-channel 0-10V industrial voltage DAC module. Used in control scenarios that demand higher signal accuracy...

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?

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...

The Raspberry Pi is an amazing single board computer - and one of the best parts is that GPIO connector! 40 pins of digital goodness you can twiddle to control LEDs...

If you've ever said to yourself, "Gee, I wish I had eight 12-bit DACs that came in a single package", well I have good news. The Adafruit...

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

Breathe easy, knowing that you can track and sense the quality of the air around you with this PM2.5 Air Quality Sensor with I2C Interface particulate sensor.

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.

DAC, is a unit with the ability to convert digital signal to analog signal (voltage waveform signal) with support for audio waveform and more. It integrates a 12-bit high resolution DAC chip named MCP4725 which has an on-board non-volatile memory (EEPROM). The unit communicates with the M5Core using the I2C protocol.
