This little instrument, named as Pico C, can be used to measure capacitances down to fractions of a picofarad. It built based on ATtiny2313 microcontroller. It has range: <1 pF to 2000 pF (guaranteed); 2500 pF possible and resolution: 0.1 pF. To read the result, this low cost C meter comes with 2 lines LCD. The project is easy to calibrate with 1000pF 1% reference capacitor.
This tiny capacitance meter is good tools for RF designers and radio amateurs. Since many built-in capacitance meter digital multimeters comes with lowest measuring range of 2000 pF.
