The SD card moves over as is, so: - pi_standard_setup can install the Pi 5 kernel (linux-image-rpi-2712, an arm64 package on the armhf userland), which a Pi 4 image lacks. Opt-in via pi_standard_setup_install_pi5_kernel. - The Pi is powered through the HiFiBerry board's GPIO header, so it cannot negotiate a 5A supply and would cap USB at 600mA. pi_hifiberry_amp sets usb_max_current_enable=1 when hifiberry_powers_pi is true (default false). - The DHT22 poller is off: Adafruit_DHT bit-bangs BCM283x registers, which the Pi 5 no longer has (GPIO sits behind the RP1 chip).

pi_hifiberry_amp
Deactivates the Pi's onboard analog audio and activates a HiFiBerry amp/DAC overlay instead.
Key vars: hifiberry_overlay, hifiberry_powers_pi
hifiberry_powers_pi (default false) is for a Pi fed through the HiFiBerry board's
GPIO header. On a Pi 5 that sets usb_max_current_enable=1, or USB is capped at 600mA.
