Orange Pi model names hide real differences: RK3588S vs full RK3588, 26-pin vs 40-pin headers, on-board eMMC and Wi-Fi only on some models, and power supplies from 5 V / 2 A to 5 V / 5 A. A side-by-side table from the official product pages.
Orange Pi names sound incremental, but the boards differ in SoC, header, storage and power. Pick by the row that matters for your project, not by the number in the name. All values below are from the official product pages at the time of writing; check the page again before ordering, since Orange Pi notes specs can change between batches.

Naming pitfalls
- 5 vs 5B: same RK3588S and 26-pin header. The 5B adds eMMC and Wi-Fi 6/BT 5.3; the plain 5 has neither on board.
- "5" boards are not all the same chip: 5 Plus and 5 Max have the full RK3588; 5, 5B, 5 Pro and CM5 have the RK3588S (fewer I/O lanes, e.g. the 5's M.2 runs PCIe 2.0 per the existing Orange Pi 5 item).
- Header size: 26-pin (5, 5B, Zero 3, RV2) vs 40-pin (5 Plus, 5 Max, 5 Pro, 3B, Zero 2W). Neither makes Raspberry Pi HATs work (see the GPIO compatibility warning).
- Power: the product pages for the 5 Max, 5 Pro and RV2 specify 5 V / 5 A, so a 3 A supply that is fine for a Zero board is below spec for them.
- RISC-V (RV2): the product page lists Ubuntu 24.04 only; Arm-only software (e.g. some NPU tools, prebuilt containers) won't run.
