This is a standalone DC voltage meter. It measures 4.5V-30V with 1% accuracy. Best suitable for battery level display.

The digital multimeter (DMM) is an essential tool in every electronic enthusiasts arsenal. The SparkFun Digital Multimeter, however, is not your average multimeter, it features a loud continuity sound, current/voltage sense, and quality probes. You can use the multimeter to measure DC and AC voltage, DC current, resistance, continuity, and test diodes. With this version we’ve done away with the bright flashy colors that can get us into trouble and gone with a nice, neutral gray. This multimeter should provoke no strong feelings one way or the other, we know this because our guts say “maybe.”

Peep this NeoPixel RGBW Neon-like LED Flex Strip with Silicone Tubing! OK its a bit of a mouthful but check out the beautiful pics! It has a diffused look like neon, but without the need for expensive transformers, glass tubing, inert gasses, or a Las Vegas casino license. They look great, are super easy to use, and are a great way to make your projects light up!

Fancy new dual-sided NeoPixel strips are a great alternative for folks who have loved and used Adafruit LED strips for a few years but want gorgeous, glowy light from both sides! These are called "120 LED per meter" because they have the same density as 60 LED per meter strips, and then of course, two LEDs on either side. Both top and bottom LED in each segment will always display the same color. You can run them along a thin edge and curve them around shapes and corners. These look awesome for accent lighting, backlighting, edge lighting, etc!

This analog panel meter measures DC voltage from 0-5 volts with 2.5% accuracy. It has a clear and easy to read scale and an adjustable dial. These come in handy for measuring the output of sensors with 5V ranges.

Put a voltage meter anywhere with this very handy display. This panel meter simply connects to whatever DC supply you are trying to track, easy to wire up! Simply...

This non-invasive current sensor (also known as a “split core current transformer”) can be clamped around the supply line of an electrical load to tell you how much current is passing through it. It does this by acting as an inductor and responding to the magnetic field around a current-carrying conductor. By reading the amount of current being produced by the coil, you can calculate how much current is passing through the conductor.

I2C stands for Inter-Integrated-Circuit communications, its meant for short distances on a PCB or subassembly. But, hey, Adafruit are engineers and Adafruit like to push the limits of technology, right? So why not try to have I2C run over a meter long cable, or even longer?
