Are you low on I/O? No problem! The SX1509 Breakout is a 16-channel GPIO expander with an I2C interface – that means with just two wires, your microcontroller can interface with 16 fully configurable digital input/output pins. But the SX1509 can do so much more than just simple digital pin con..
This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. This chip is like a rotary switch - it internally routes the common pin (COM in the schematic, SIG on the board) to one of 16 channel pins (CHANxx). It works with both digital and analog signa..
The SparkFun Qwiic Pro Micro is a revision of the original Pro Micro and is, overall, functionally the same as the previous version. The board is the same size as the original Pro Micro but we added a few additional features by shrinking down some components on the board such as a reset button, Qwii..
The RedBoard Artemis ATP is affectionately called 'All the Pins!' at SparkFun. The Artemis module has 48 GPIO and this board breaks out absolutely every one of them in a familiar Mega like form factor. What's with the silkscreen labels? They're all over the place. We decided to label..
The Artemis Nano is a party on the front and business on the back. And that's by design! All the important LEDs, connectors, labels, and buttons are presented on the front for the best user experience with all the supporting circuitry on the rear of the board. The RedBoard Artemis Nano is a mini..
This is the Teensy 4 Audio Shield (Rev D) that can be added to a Teensy 4.0 for your next audio project. The shield provides you with an easy-to-use tool to add high quality 16 bit, 44.1 kHz sample rate audio to your Teensy. With the audio library you will be able to use both the input and output si..
The Teensy 4.1 is the newest iteration of the astoundingly popular development platform that features an ARM Cortex-M7 processor at 600MHz, with a NXP iMXRT1062 chip, four times larger flash memory than the 4.0, and two new locations to optionally add more memory. The Teensy 4.1 is the same size and..
The SparkFun 9DoF Sensor Stick is an easy-to-use 9 Degrees of Freedom IMU. The Sensor Stick deftly utilizes the LSM9DS1 motion-sensing system-in-a-chip, the same IC used in the SparkFun 9DoF IMU Breakout. It houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer – nine degree..
The CCS811 Air Quality Breakout is a digital gas sensor solution that senses a wide range of Total Volatile Organic Compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. VOCs are often categorized as pollutants and/or sensory irritants and can come from a variet..
The SparkFun ESP8266 Thing is a breakout and development board for the ESP8266 WiFi SoC – a leading platform for Internet of Things (IoT) or WiFi-related projects. The Thing is low-cost and easy to use, and Arduino IDE integration can be achieved in just a few steps. SparkFun has made the ESP8..
The Si7021 is a low-cost, easy-to-use, highly accurate, digital humidity and temperature sensor. This sensor is ideal for environmental sensing and data logging and perfect for build a weather stations or humidor control system. All you need are two lines for I2C communication, and you’ll have..
