The Si7021 is a low-cost, easy-to-use, highly accurate, digital humidity and temperature sensor. 

Life has its ups and downs, so why not measure them? The MPL3115A2 is a MEMS pressure sensor that provides Altitude data to within 30cm (with oversampling enabled).

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

This is your standard solderless breadboard - three binding posts, two power buses, black aluminum plate backing.

We have no idea what USB device you are hooking up to, but if you want to access the microUSB port on something, you might want this.

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

This is a simple three wire cable. Great for jumping from board to board or just about anything else.

The serial enabled LCD allows you to control a parallel based LCD over a single-wire serial interface. Included in this product is a white on black 16x2 LCD connected to a serial backpack.

This is a very simple breadboard power supply kit that takes power from a DC wall wart and outputs a selectable 5V or 3.3V regulated voltage. 

This is a basic breakout board for the FTDI FT232RL USB to serial IC. 

The kit does not require any soldering and is recommended for anyone with a drive to learn more about Blynk and its uses. So if you are looking for a new challenge or a way to get in on the IoT craze, check out the SparkFun IoT Starter Kit with Blynk Board!

Microsoft and SparkFun have teamed up to bring you some IoT (Internet of Things) fun. The Microsoft Azure IoT Starter Kit for the SparkFun Thing Development Board has been designed to help you seamlessly connect your device to the cloud with Microsoft Azure IoT. 

This 2xAA battery holder puts a nice finishing touch on your battery powered project. 

150 LED RGB ribbon kit SMD IP65 multi colors for decoration. Great for lighting spaces, giving color and ambience to projects.

This Silicon Diode (1N4148) has a fast switching speed, silicon epitaxial planar construction, lead free finish and it is RoHS compliant.
