Need range? The 2.4GHz Large Duck Antenna 5dBi with Reverse Polarized - SMA RF connector is perfect for you.

The 2WD mobile platform for Arduino is a small, low-cost mobile platform for use with a standard Arduino microcontroller . The robot comes as a kit that includes two drive motors, wheels (and rear caster), frame and all mounting hardware . The main structure and mechanical parts of a robot.

This 12-inch (30-cm) cable has 26 AWG wires and a 3-pin female JST PH-style connector that works with Sharp analog distance sensors that have mating PH connectors. The other ends of the wire are terminated with female pins for 0.1" housing. The wire color scheme matches the Sharp distance sensor pinout: red for power, black for ground, and white for signal.

This 4-digit 7-segment shield has 5 buttons that can be used as menu selection buttons or control buttons, using I2C to conduct the digital call.

Classic 9V connector terminated with 2-pin polarized Molex connector.    

A-Star 32U4 Prime SV

This AA boost module integrates with TI's TPS61032 auxiliary chip, which is capable of producing 5V 1A with input above 1.8V . The only difference between V1 and V2 is to change the output current from 2A to 1A.

At ElectroFun we have a few different GPS modules, but none that met all of our wishes - that's why we acquired this small GPS card. This is the Ultimate GPS Module.

Arduino is a huge ecosystem, so if there is a way to adapt the Raspberry Pi interface to Arduino pinning, you can create fantastic designs using the best of both worlds. This Adapter Board was created just for this.

This is an os card for our RFID readers . The SparkFun L eid RFID Breakout converts the 2mm pins to the breadboard in a friendly 0.1 "headers. With this ability the ID-3LA, ID-12LA, and ID-20LA you can weld the reader directly to the header or use the 2 mm connectors

The TL431A is a three-terminal adjustable regulator with a guaranteed thermal stability over applicable temperature ranges.

AirPods-Style Wireless Bluetooth Headsets. Enjoy Music without Cables in the way.

Basic breakout board for the TEMT6000 Ambient Light Sensor.

The flame sensor can be used to detect fire or another wavelength in light from 760 nm - 1100 nm.

ORP (Oxidation-Reduction Potential) is a measure of oxidation capacity and reduction of the aqueous solution. Unlike a pH measurement that follows a logarithmic curve and therefore requires more calibration adjustments, O RP follows a linear relationship and does not need any instrument adjustments as well as electrode maintenance. ORP is a reliable method of measuring water quality and provides the operator with a unique measurement value.

This analog panel meter measures DC voltage from 0-5 volts with 2.5% accuracy.

This sliding position sensor is based on sliding potentiometer position sensor and can be easily combined with the Arduino sensor/IO expansion board .

Arduino Expansion Shield for Raspberry Pi B - DFRobot

These headers are made to work with the Arduino Uno R3, Leonardo and new Arduino boards going forward.
