The Raspberry Pi 4B is as power-hungry, if not more, as its predecessors. It is important to have a [https://www.raspberrypi.org/documentation/hardware/raspberrypi/power/README.md sufficient enough power supply] or ''weirdness'' may happen. Weirdness may include: | The Raspberry Pi 4B is as power-hungry, if not more, as its predecessors.

Note that the Type-C USB receptacle for the Raspberry Pi 4B '''does not implement Power Delivery (USB PD)'''. This means that it is limited to whatever the power supply will provide when not negotiating power, which is most likely 5V at some undetermined power level. | Note that the Type-C USB receptacle for the Raspberry Pi 4B '''does not implement Power Delivery (USB PD)'''.

=== Audio not playing and Bluetooth: no controller available === | |||
On the Raspberry Pi kernel, the jack may never play audio, and no Bluetooth devices may ever be found. To get this to work, it is recommended to switch to the mainline kernel. See [https://github.com/NixOS/nixpkgs/issues/123725 nixpkgs#123725] for more info. | |||
