KAmodKB4x4 - module of a 16-button 4 × 4 matrix keyboard 15-Bit ADC PSU: Power is taken from

PSU: Power is taken from RPI and then heavily filtered for each rail

5 Hz Sampling Rate ( einmal jede zweite Sekunde)

Das PoE HAT benötigt dabei eine Eingangsspannung von 48 V Gleichstrom

you can connect an external 5V source and use the alternative connections on the driver board (or add supplementary wires directly to 5V/GND on the LED boards)
