Analog panel meters are arguably not as blingy or flashy as LEDs, but their simplicity adds a touch of elegance and makes them easier to read quickly.This Large 3V Panel Meter is about handheld-size, with one scr...

SKU: SF-BOB-12052 | Brand: SparkFun

Odometers are extremely useful for cars, they tell you how far you have gone, wouldn’t it be nice if you were able to have a device that does the same for electrical current? The LTC4150 SparkFun Coulomb Counter Break...

SKU: SF-SEN-12040 | Brand: SparkFun

The INA169 is a “high-side current monitor,” which means that you place a resistor (a “shunt resistor”) on the positive power rail and the INA169 measures the voltage drop across that resistor. The INA169 outputs a sm...

SKU: AF-460 | Brand: Adafruit

Put a voltage meter anywhere with this very handy display. These are often used by RC hobbyists for keeping track of batteries but we thought it would be great on a breadboard or enclosure. This is the 2-wire versi...

SKU: AF-5832 | Brand: Adafruit

This breakout brings the INA228 power monitoring chip out to an easy-to-use board for measuring DC current, bus voltage and calculated power on either the high side or the low side of a circuit. It combines a wide com...

SKU: SF-TOL-20680 | Brand: SparkFun

Keep an eye on your single-cell LiPo battery before your project suddenly runs out of power. This compact fuel gauge board sits in circuit with your battery and reports the relative state of charge using the MAX17043 ...
