This Thermocouple Connector is perfect for bridging the gap between Type-K thermocouples with standard connectors with a PCB. This little connector is actually the exact part we recommend using with our SparkFun Thermocouple Breakout!...

This is a board designed for opto-isolation . This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system. This board electrically isolates a controller from the high-power system by...

This is a piezoresistive force sensor from Tekscan. The harder you press, the lower the sensor’s resistance. Pressing hard, the resistance changes from infinite to ~50k. The sensor itself is thin and flexible, but the resistance does not...

Want to sound like a robot? The HT8950 is a single chip CMOS LSI voice modulator ICs which provide seven steps to shift the frequency of an input voice, producing a dramatic change in the output. The HT8950 provides two special effects:...

The SparkFun SAM-M8Q GPS Breakout is a high quality, GPS board with equally impressive configuration options. The SAM-M8Q is a 72-channel GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou...

This is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). This allows for faster transfer rates...

The LilyPad Arduino 328 Main Board is an Arduino-programmed microcontroller designed to be easily integrated into e-textiles and wearable projects. It offers the same functionality you find in other Arduino boards, in a lightweight,...

A small, but very mighty power supply. This board was designed to be as small and inconspicuous as possible. The nice thing about LiPower is the ability to use rechargable Lithium Polymer batteries. These batteries are smaller, flatter,...

The MPR121QR2 is an I 2 C driven capacitive touch sensor controller, capable of managing up to twelve electrodes. The chip also has eight LED driving pins, which, when not configured to control electrodes, can be used to drive LEDs. The...

The LPR5150AL is low-power two-axis micromachined gyroscope able to measure angular rate along the pitch and roll axes. All required electronics are integrated onto a single chip with the sensor. The LPR5150AL has a full scale of ±1500...

The KTA-223 Relay Board is a USB or RS485 controlled module that can interface a PC to eight or more SPDT relays. This could be very useful for controlling real world devices - such as lights and sprinkler systems - and reading sensors...

This is a thermal printer like you would find on a cash register or adding machine. It will print simple strings passed to it via TTL serial, bitmap images (poorly) and it even generates several different formats of barcodes! The thermal...
