Multimeter click - MikroElektronika Voltage, Current, Resistance, & Capacitance Security Modules stereo output Speaker 4PIN speakerMultimeter click MikroElektronika Voltage, Current, Resistance, & Capacitance Multimeter click is a Click board designed to measure voltage, current, resistance, and capacitance properties of the components, connected to the input terminals. Each property measurement is done on a separate terminal. Each measurement section conditions the input signal from the respective input terminal and forwards it to a four channel 12 bit A D converter. All the
