Volt Tattler

The Volt Tattler 2 is a microcontroller based D.C. system voltage monitor with programmable voltage thresholds to monitor and warn of power system problems. This simple but very useful kit is ideal as a novice construction project and every home and portable station should have one.


  • Simple through-hole construction
  • Draws only around 1 mA in normal use.
  • Reverse polarity protection.
  • Thresholds programmable over a range of 4V to over 27V.
  • Single button programming with audio feedback.
  • Audibly announces activation at power on and indicates it is monitoring with a flashing green LED.
  • Audibly announces by Morse code when input voltage exceeds user programmed thresholds.
  • Flashing Red and Yellow LEDs indicate that a voltage limit has been exceeded.
  • 3V digital status signals are available on a header
  • Cheap protection for all low voltage DC equipment.
