Frequency Counter Kit

Product Description

Replacement: KIT-10014. We are now building these in-house. This page is for reference only.

Description: The FunCount kit from Nuxie includes everything needed to build a frequency counter capable of measuring frequencies from 1Hz to over 2MHz. Perfect for use with the FunGen also available.



This simple design uses the 20 pin ATTiny2313 microcontroller to measure frequencies from 1Hz to over 2MHz. The PCB also provides access to the unused microcontroller pins, so that the board can also be used as a general purpose AVR development board with an LCD.



 The frequency is displayed on a standard HD44780 16x2 LCD. A bright white text, blue backlit LCD is included with the kit.



The input voltage needs to have at least a 3V swing to be able to trigger the counter.



The kit requires a regulated 5VDC supply.
