5 PCS Logic Test Pen Module

Description:
5 PCS Logic Test Pen Module package contains 5 pen-shaped, handheld, and user-friendly logic tester, with an elastic line (DuPont material made) to touch test point of the power supply, circuit, and boards. This tester is a handy size and easily can check the voltage level of suppliers points and eliminates needing a multimeter tool. It is a portable and handheld devices, which using this tester, troubleshooting of digital electronic circuits and boards, especially debugging  Arduino board can conveniently and quickly be performed.
It can be supplied with logic 3.3V  or 5V and shows the result of measuring of voltage level in three states as below:
Red light (high level)  for test point voltages above 2.4V  at 5V supplied (for test point voltages above 1.49V  at 3.3V supplied)
Green light (low level) for test point voltages under 0.6V at  5V supplied (for test point voltages under 0.39V  at 3.3V supplied)
Blue lights for 0.6V up to 2.4V or disconnected at 5V supplied (for 0.39V up to 1.49V or disconnected at 3.3V supplied)
