Knowledge about OpenWrt
- Armbian on Banana Pi: BPI-M5, M7, M4 Zero, M2S and F3 have 'Standard support', BPI-R4 only 'Community support'recommendation · unverified · Before choosing Banana Pi's own images, check the board on armbian.com. At the time of writing, the BPI-M5, BPI-M7, BPI-M4 Zero, BPI-M2S and BPI-F3 pages show Standard support, the BPI-R4 page Community support. Vendor images can be old: the BPI-M5's newest Ubuntu image on its docs page is Ubuntu 20.04 from 2023.
- Banana Pi BPI-F3: a RISC-V SBC with the SpacemiT K1, and which operating systems it runsguide · unverified · The BPI-F3 uses the SpacemiT K1, an octa-core 64-bit RISC-V chip with 2.0 TOPS of AI compute. Banana Pi's docs list Bianbu Linux (SpacemiT), an OpenWrt 23.05.2 source tree, Armbian and an ArchLinux port; Armbian shows it with Standard support. It has a 26-pin header and a -40 to 85 °C operating range.
- Banana Pi BPI-R3: boot switches, SD/NAND/eMMC install order, and the SFP and serial-adapter pitfallsprocedure · unverified · The BPI-R3 boots from microSD, SPI-NAND, SPI-NOR or eMMC depending on four DIP switches. microSD and eMMC share pins, so installing OpenWrt to eMMC goes via SPI-NAND. Its SFP cages only speak 2.5GBase-X, and some USB-serial adapters break Wi-Fi initialisation.
- Banana Pi BPI-R4: no Wi-Fi on the board, a 19 V supply for the Wi-Fi 7 card, and the 8 GB RAM trapwarning · unverified · The BPI-R4 (MT7988A) brings Wi-Fi through miniPCIe cards, not onboard radios. OpenWrt's device page says the optional Wi-Fi 7 card needs a 19 V / 3.2 A supply and a switch set before installation, and that a 4 GB image limits 8 GB boards to 4 GB unless a compatible BL2 bootloader is used.
- Banana Pi router boards for an IoT gateway: BPI-R3 vs BPI-R3 Mini vs BPI-R4 vs OpenWrt Onecomparison · unverified · All four are MediaTek Filogic boards aimed at OpenWrt. The OpenWrt One is the OpenWrt project's own board with an unbrickable NOR recovery system; the R3 Mini is compact with two 2.5GbE ports and a 5G slot; the R3 adds SFP and five gigabit ports; the R4 adds 10G SFP and Wi-Fi 7 via cards.
