Details

This simple Platino-based Transistor Tester is designed to test transistors in a simple and portable way. Since it is tedious to read the markings on the transistor devices and to look up its characteristics in datasheets, a handy transistor tester makes its way in such scenarios. The Platino Transistor tester not only identifies the leads of the device but also the type and characteristics like Hfe of the device. The simplified design of Elektor’s Platino board makes it simpler to extend its capability to develop devices of complex functionality with a few enhancements.

Specifications:

  • DC Input: 12V to 18V DC.
  • Elektor Platino with ATMEGA32 microcontroller.
  • 20 X 4 LCD Display.
  • Elektor’s USB to Serial BOB module interfacing for debugging.
  • Pluggable terminal block for easy mounting of transistor device to be tested.

Features:

  • Identifies transistor type, leads and characteristics.
  • Indicates faulty or no transistor.
  • Results can be viewed on LCD as well as serial terminal simultaneously.
  • Easy and portable design.
