Products from SparkFun Electronics

If you’re ready to step your Arduino game up from older 8-bit/16MHz microcontrollers, the SparkFun SAMD21 Dev Breakout is a great landing spot. The SparkFun SAMD21 Dev Breakout is an Arduino-sized breakout for the Atmel ATSAMD21G18, a...

The SparkFun MIDI Shield board gives your Arduino-based device access to the antiquated, but still widely used and well supported MIDI communication protocol , so you can control synthesizers, sequencers, and other musical devices. The...

Are you low on I/O? No problem! The SX1509 Breakout is a 16-channel GPIO expander with an I 2 C interface – that means with just two wires, your microcontroller can interface with 16 fully configurable digital input/output pins. But the...

The LSM6DS3 is a accelerometer and gyroscope sensor with a giant 8kb FIFO buffer and embedded processing interrupt functions, specifically targeted at the cellphone market. Due to the capabilities and low cost of the LSM6DS3 we’ve...

The SparkFun Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. By connecting the amplifier to your microcontroller you will be able to read the changes in the...

The Spectrum Shield enables your Arduino with the capability of splitting a stereo audio input into 7-bands per channel. You can then read the amplitude of each channel using the ADC on your Arduino allowing you to control everything...

The BLE Mate 2 closely resembles a breakout board, in that nearly every pin on the on-board BC118 module is made available to access. This board is actually a close cousin to our Gold and Silver Bluetooth Mates and functions in a very...

This is the Magnetic Door Switch Set, a small reed switch assembly specifically designed to alert you when doors, drawers, or any other aperture opens. These types of switches are primarily used in home security systems. One half of the...

The SparkFun MAX31855K Thermocouple Breakout is a simple 14-bit resolution, SPI-compatible, serial interface thermocouple digitizer that makes reading a wide range of temperatures possible. A thermocouple works by taking two wires made...

This is a stainless steel, Type-K Thermocouple probe. A thermocouple works by taking two wires made of dissimilar metals, connecting them at the two ends, and making a temperature gradient between one end and the other (a ‘hot’ end and a...

This is the SparkFun Rotary Switch Breakout, a very simple board designed to easily provide you access to each pin on our 10-position rotary switches. This breakout allows you to easily add a rotary switch to your next project without...

This is a single pole, 10 position rotary switch able to select up to 10 different states in a durable package. Unlike our other rotary switch, this model is much more robust and capable of handling larger currents and voltages. With a...
