Put this onto pins 19 and 21 for LCDd? https://www.crystalfontz.com/product/cfa635tmlkl-20x4-uart-display-module-text

Turn some GPIO pins into LEDs to emulate LAN activity lights:

/ {
  leds {
    lan-link-led {
      label = "lan:link";
      default-state = "off";
      gpios = <&gpio1 RK_C4 GPIO_ACTIVE_HIGH>; // Pin 3 on Pi-2 Connector
    }
    lan-act-led {
      label = "lan:activity";
      default-state = "off";
      gpios = <&gpio1 RK_C5 GPIO_ACTIVE_HIGH>; // Pin 5 on Pi-2 Connector
    }
  }
}
