How a Key Matrix Work - PCB Heaven
my circuit has 4-18-4 pins. So obviously. it's for 8x18 matrix. Base on the specs, it draws 250mA. Since usb ports supplies 500mA. Can I just do a parallel connection to get the other 250mA? I will use that 250mA to power another circuit. That circuit will be use to automate the clicks of the keyboard's circuit
Keyboard matrix circuit - Wikipedia
Keyboard matrix circuit. A keyboard matrix circuit is a design used in most electronic musical keyboards and computer keyboards in which the key switches are connected by a grid of wires, similar to a diode matrix. For example, 16 wires arranged in 8 rows and 8 columns can connect 64 keys — sufficient for a full five octaves of range (61 notes).
