• 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-M4 Zero: a Pi Zero W-sized board with eMMC, and the K016 Wi-Fi module that has no 5 GHzguide · unverified · The BPI-M4 Zero has the form factor and 40-pin connector of the Raspberry Pi Zero W, an Allwinner H618, 2 or 4 GB LPDDR4 and 8 or 32 GB eMMC. Banana Pi notes that boards with the K016 Wi-Fi module don't support 5 GHz Wi-Fi. Armbian shows Standard support.
• 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 for IoT and home servers: BPI-M7 (RK3588) and BPI-M5 (Amlogic S905X3)guide · unverified · Banana Pi spans many SoC vendors. Two representative boards: BPI-M7 with RK3588, up to 32 GB RAM, eMMC, PCIe 3.0 x4 NVMe and dual 2.5G Ethernet; BPI-M5 with Amlogic S905X3, 4 GB RAM, 16 GB eMMC and four USB 3.0 ports.
• 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 power supplies: 5 V over USB for the M boards, 12 V or 19 V barrel jacks for the router boardswarning · unverified · Banana Pi boards don't share one power standard. The BPI-M5 and BPI-M4 Zero take 5 V / 3 A over USB, the BPI-R3 needs 12 V / 2 A, the BPI-R4 12 V / 5.2 A or 19 V / 3.2 A, and the BPI-R3 Mini 12 V (20 W) or USB-C PD. Check each board's page before reusing a supply.
• 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.
• GPIO on Banana Pi: the RPi.GPIO and WiringPi ports only do simple I/O, and BCM numbers are translatedwarning · unverified · Banana Pi's docs point to ports of WiringPi (with gpio readall) and RPi.GPIO for boards like the BPI-M5, M2S, M4 Zero and F3. The RPi.GPIO port states that only simple I/O works — PWM, events and analog read are not implemented — apps need root, and BCM numbers are mapped to Banana Pi pins internally.
