MIKROE-2376

NE555 Timer Click Board

**C Meter click is a mikroBUS** add-on board with 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:**

* NE-555 timer IC

* Astable multivibrator circuit

* Plates and sockets for placing capacitors

* 5V power supply

* Adjustable logic level 3.3V or 5V

* Screw terminals allow use with multimeter probes

* Ready-to-use examples save development time

* mikroBUS™ form factor simplifies integration

The board has four different-sized plates for placing SMD capacitors covering standard SMD packaging dimensions as well as a socket for inserting a thru hole capacitor.

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 multimeter probes.

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