SparkFun Electronics will be closed on November 26, 2020 and November 27, 2020 for the Thanksgiving holiday. We will begin normal operations at 9:00 AM Mountain Time on November 30, 2020.
The Multimeter Kit provides you with everything you need to make your own multimeter capable of measuring voltage (0-30VDC, 0.05 resolution) current (0-500mA, 1mA resolution) and resistance (0-100kΩ). The resistance mode also includes a continuity test: the buzzer will sound when the resistance probes are shorted together, this is one of the more handy tools of any multimeter.
Using the Multimeter Kit is very straightforward. To measure voltage connect your probes to the 'Voltage' and 'Common' pins, for current measurement the 'Current' and 'Common' pins. Resistance measurement uses the 'Res-1' and 'Res-2' pins. The decimal points are used in resistance measurement mode to indicate 10kΩ and 100kΩ ranges.
This kit now includes test probe cables! Batteries, however, are not included. Also, we've changed some footprints to make it easier to assemble without bending components' legs around. The buzzer has been moved from one pin to another as well so this revision does have slightly different firmware from the last.
Note: using the resistance measurement mode on live circuits is not recommended. Also, do not test current or voltage on devices that may be outside the measuring range (no negative voltages or currents)! The multimeter is very simple, and won't replace your Fluke meter, but it works perfectly for simple troubleshooting.
Note: Brought back for only a limited time. We found some remaining stock and decided to make what little we had left available to those who may want it.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.
