SparkFun - Frequency Counter Kit


Availability: Out of stock

SKU:

S-KIT-10014

Quick overview

Description: This kit is a re-hash of Nuxie's FunCount frequency counting kit. It includes everything you need to build a frequency counter capable of measuring frequencies from 1Hz to over 6MHz. The measured frequency is displayed on a 16x2 black on green LCD.

Our new design is based on the popular ATmega328. The ATmega comes pre-programmed with both the frequency counting firmware, and a serial bootloader, so you can program it as you would an Arduino. If you want to program it via Arduino, you'll need a FTDI Basic Breakout. Unfortunately, a hardware layout mishap (TX-O and RX-I should be swapped) means you'll need to do a bit of creative wiring to connect the Counter to your FTDI board. Unused pins of the ATmega328 are broken out for all your custom firmware desires.

The ATmega328 runs at 16MHz, and should be able to reliably count frequencies up to around 6.4MHz (assuming a 50% duty cycle). Voltage supplied to the kit should be 5VDC. The voltage input on the frequency pin should not exceed the supplied voltage, and should not go below 0V.

The kit includes a 3-pin JST male connector, so you can use this wire to deliver +5V, ground and the frequency signal to the Counter. You'll also be able to piggy-back the counter onto our soon-to-be-released Function Generator Kit.
