• 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 lineup decoded: M boards, R router boards, F RISC-V boards, and which SoC is insideguide · unverified · Banana Pi sells many boards built on chips from different vendors. Group them by SoC: MediaTek Filogic router boards (BPI-R), Allwinner and Amlogic boards (BPI-M, P2 Zero), and RISC-V SpacemiT K1 boards (BPI-F3, CM6). Software support follows the SoC, not the brand.
• 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.
