Openwrt for Raspberry Pi 5

The Raspberry Pi is a series of single-board computers using Broadcom SoCs and lack an Ethernet Network Switch.

Raspberry Pi 1, 2, and 3 are compiled with the ARM hard-float kernel ABI, this means that non-integer math is done in hardware instead of in software. Those series have somewhat reached legacy status.

Raspberry Pi 4 has significantly higher spec CPU, RAM, and storage while maintaining the form factor, low power consumption, and passive cooling. Its capability can exceed many top tier routers. However it requires adding a USB 3.0 to gigabit ethernet adapter, gigabit switch, and wireless access point to reach similar networking functionality.

Raspberry Pi 5 released in late 2023 with improvements including a power button, RTC, and 2-3x the performance of the Pi 4.
