The Raspberry Pi 4 launched earlier this year to critical acclaim, thanks to upgrades including but not limited to a more powerful processor, the first new graphics processor in Raspberry Pi history, true gigabit Ethernet connectivity, and PCI Express-connected USB 3.0 ports.
It also drew some criticism for its higher-than-expected power draw and, correspondingly, heat output — something the engineers at the Raspberry Pi Foundation have been working to address in a series of firmware updates.
