C Meter click

From MikroElektonika Documentation

C Meter click has circuitry for measuring the value of capacitors. The design is based on a NE-555 timer/square-wave generator. The chip is implemented in an astable multivibrator circuit with fixed resistors and adjustable capacitors.

Features and usage notes

C Meter click has four different-sized plates for placing SMD capacitors covering standard SMD packaging dimensions as well as a socket for inserting a thru hole resistor. Each plate is labeled with package size in standard imperial measurements:
1210 3.2mm x 2.5mm
1206 mm x mm
0805 mm x x1.25 mm

Schematic also available in PDF
0603 mm x mm

The board outputs a square wave frequency through the INT pin. Depending on the capacitor placed on the board, the value of this frequency changes. The value of a capacitor can be inferred using a simple algorithm shown in the Libstock code example .

Onboard screw terminals are placed to allow the click to be used with oscillator probes.

C Meter click is designed to use a 5V power supply, but can work with either 3.3V or 5V logic levels.
