The general design is done all that s left is to decide on which diode is going to be used. Leds do not work as diodes in a keyboard matrix. What diode to use in keyboard matrix pcb.
Diodes are one way valves for electricity. That being said diodes restrict the direction in which current can flow in your switch matrix. This allows one to build full nkro keyboards n key rollover.

Active 7 months ago. Of course this isn t real od but it solves the current loop problem in a keyboard matrix. This way the pin set to 1 will never source current and this nearly makes it an od pin.
By inserting a diode between every column pin and the column wire which later goes to every switch in the column we can only allow currents to flow into the pins. Add to cart new. See ordering details below.
