What is it?

A micro current measurement meter adapter. Connect to a multimeter to read out micro current on the voltage scale.

Applications: Measuring microprocessor sleep current, measuring RTC operating current, etc.

Fully assembled and tested, batteries included.

Why did you make it?

I wanted an EEVBLOG µCurrent, but they are scarce these days, so I built up this simplified version. This is not a µCurrent clone, but it is based on the core µCurrent Original design. Unlike the µCurrent, which measures bipolar current, this device measures positive current only. This product is built using high quality 0.05% tolerance parts in the measurement circuits to ensure good final accuracy.

What makes it special?

• Simple design - two ranges: 0-5000nA and 0-5000µA
• Selectable 10X Attenuator for increased range and reduced noise measurements
• Input shorting switch
• Battery powered - 2 x CR2032
• Battery test feature
• Open Source Technology
