Low Cost I/O Logic Tester

Low Cost I/O Logic Tester 
Low Cost Logic Tester is a module that consists of 4 pieces LEDs as outputs and 4 tactile switches as inputs. This module can be used as a tester for logic input and output ports of the microcontroller. 

- 4 LEDs with the configuration of active low (logic 0 will activate the port LED).
- 4 tactile switches with active low configuration (tactile switch is pressed will produce a logic 0).
- Can be used on port PPI (82C55) and port 1 microcontroller.
- Fully compatible with the +5V logic level microcontroller
