STEMMA
WHAT IS STEMMA? STEMMA is a plug-and-play board and sensor system that lets you quickly plug together various devices and accessories, without any soldering! STEMMA uses 3-pin cables for simple analog and digital devices, like relays and buttons. For more complex sensors and displays, we use a 4-wire I2C connection. For larger boards and devices we use a Grove-compatible connector, for smaller ones we use a Qwiic-compatible connector called STEMMA QT.
As all STEMMA sensors have level shifting and voltage regulation, you can use them safely with any 3 to 5V power and logic device - from microcontrollers like Arduino-compatibles, to full Linux single board computers like the Raspberry Pi. We even have USB to I2C adapters that let you connect STEMMA devices directly to a computer without any microcontroller programming required! Then, use our Arduino or CircuitPython/Python libraries and examples to easily get your electronics project working on any platform with STEMMA and STEMMA QT.

Most low cost soil sensors are resistive style, where there's two prongs and the sensor measures the conductivity between the two. These work OK at first, but eventually start to oxidize because of the exposed metal. Even if they're gold plated! The resistivity measurement goes up and up, so you constantly have to re-calibrate your code. Also, resistive measurements don't always work in loose soil. This design is superior with a...

The Adafruit PCT2075 Temperature Sensor is a 'code compatible' drop-in replacement for a very common I2C temperature sensor, the LM75. Compared to the LM75, however, the 11-bit ADC in the PCT2075 provides more precise measurements when compared to the LM75's 9-bit ADC. Additionally, because the PCT2075 allows the address pins to work in three states (high, low, floating), you can have 27 PCT2075s on the same bus as opposed to only 8...

It's a programmable resistor, similar to an I2C potentiometer like the DS3502 I2C Potentiometer , so why another? The big difference between the two is how the...

This tiny little servo can rotate approximately 180 degrees (90 in each direction), and works just like the standard kinds you're used to but smaller . You can use any servo code, hardware or library to control these servos. Good for beginners who want to make stuff move without building a motor controller with feedback & gear box, especially since it will fit in small places. Of course, it's not nearly as strong as a standard...

This OLED goes out to all the fans who want more pixels ! Normally our 128x64 OLEDs are the biggest ones we've stocked that can use I2C. This one is a whopping 128x128 pixels and it even has an extra bonus - it can do grayscale pixels! Yep, you get the same crispness of a monochrome OLED but with 16 levels of grayscale. This display is a petite 1.5" diagonal, but very readable due to the high contrast of an OLED display. This display is...

Sense the magnetic fields that surround us with this handy triple-axis magnetometer (compass) module. Magnetometers can sense where the strongest magnetic force is coming from, generally used to detect magnetic north, but can also be used for measuring magnetic fields. This sensor tends to be paired with a 6-DoF (degree of freedom) accelerometer/gyroscope to create a 9-DoF inertial measurement unit that can detect its orientation in real-space...

Sometimes you need to sense pressure in a damp or caustic environment. And sometimes you need to know the relative changes in pressure as well as the absolute pressure. For the times you need to do both (or either), the LPS33HW is the pressure sensor for you. Combining protection from water intrusion with support for high precision relative and absolute measurements, this sensor will do what you need. With drivers for CircuitPython, Arduino, and...

The SparkFun Qwiic HAT for Raspberry Pi is the quickest and easiest way to enter SparkFun’s Qwiic / STEMMA QT ecosystem when using that Raspberry Pi that you’ve come to know and love. The Qwiic HAT connects the I2C bus (GND, 3.3V, SDA, and SCL) on your Raspberry Pi to an array of Qwiic connectors on the HAT. Since the Qwiic system allows for daisy-chaining boards with different addresses, you can stack as many sensors as...

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 enables communication with multiple I2C devices that have the same address that makes it simple to interface with. The Qwiic Mux also has eight configurable addresses of its own, allowing for up to 64 I2C buses on a connection. To make it even easier to use this multiplexer, all...

Most accelerometers have a similar range of measurements that they can make: often around 2G - 16G. Similarly, most gyros can measure in the range of 250 degree/s to 2000 degrees/s. That's enough for many situations, however, there are many situations where it's not quite enough. When measuring things like a golf swing, soccer ball kick or perhaps a fancy racing car, you need a bit more performance out of your motion sensor. The ICM20649...

Behold, the ST LSM6DSO32: The latest in a long line of quality Accelerometer+Gyroscope 6-DOF IMUs from ST. This IMU is like a big sister to the LSM6DSOX; it has the same pinout and firmware - but the accelerometer component can go up to 32g instead of the normal 16g maximum. This IMU sensor has 6 degrees of freedom - 3 degrees each of linear acceleration and angular velocity at varying rates within a respectable range. For the...
