# Orange Pi lineup decoded: 5 vs 5B vs 5 Plus vs 5 Max vs 5 Pro, 3B, Zero 3, Zero 2W, RV2 and CM5

> 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.

## RK3588 family

| Model | SoC | RAM | Storage | Network / wireless | Header | Power |
|---|---|---|---|---|---|---|
| Orange Pi 5 | RK3588S | 4/8/16 GB LPDDR4/4X | microSD, 16 MB SPI NOR, M.2 M-key (NVMe) | 1 GbE; Wi-Fi only via optional PCIe module | **26-pin** + 3-pin debug UART | USB-C 5 V / 4 A |
| Orange Pi 5B | RK3588S | 4/8/16 GB LPDDR4/4X | **32–256 GB eMMC**, 16 MB SPI, microSD, M.2 M-key | 1 GbE, **Wi-Fi 6 + BT 5.3** | 26-pin | USB-C 5 V / 4 A |
| Orange Pi 5 Plus | **RK3588** | 4/8/16 GB LPDDR4/4X | eMMC socket, 16/32 MB QSPI NOR, microSD, M.2 M-key **PCIe 3.0 x4** | **2× 2.5 GbE**, M.2 E-key for Wi-Fi 6/BT | **40-pin** | USB-C 5 V / 4 A |
| Orange Pi 5 Max | **RK3588** | 4/8/16 GB **LPDDR5** | eMMC (socket or on-board), 16 MB QSPI NOR, microSD, M.2 PCIe 3.0 x4 | 1× 2.5 GbE, on-board **Wi-Fi 6E + BT 5.3** | 40-pin (debug UART on the header) | USB-C **5 V / 5 A** |
| Orange Pi 5 Pro | RK3588S | 4/8/16 GB **LPDDR5** | eMMC socket *or* SPI flash (empty by default), microSD, M.2 (NVMe or SATA) | 1 GbE with PoE+ (HAT required), Wi-Fi 5 + BT 5.0 | 40-pin (debug UART on the header) | USB-C **5 V / 5 A** |
| Orange Pi CM5 | RK3588S | 2–32 GB | 32–256 GB eMMC | via carrier board | 3× 100-pin board-to-board | 5 V, max. 1800 mA input |

## Smaller and different boards

| Model | SoC | RAM | Highlights | Header | Power |
|---|---|---|---|---|---|
| Orange Pi 3B | Rockchip **RK3566**, 0.8 TOPS NPU | 2/4/8 GB | eMMC module socket, 16/32 MB SPI, optional M.2 (SATA or PCIe 2.0 NVMe), Wi-Fi 5 + BT 5.0, 1 GbE | 40-pin | USB-C 5 V / 3 A |
| Orange Pi Zero 3 | Allwinner **H618** | 1/1.5/2/4 GB | Wi-Fi 5 + BT 5.0, 1 GbE, micro-HDMI | 26-pin (+13-pin via adapter board) | USB-C |
| Orange Pi Zero 2W | Allwinner **H618** | 1/1.5/2/4 GB | Wi-Fi 5 + BT 5.0, 16 MB SPI flash, mini-HDMI, 24-pin extension (USB, 100M Ethernet, IR) | 40-pin | USB-C 5 V / 2 A or 3 A |
| Orange Pi RV2 | Ky X1, 8-core **RISC-V**, 2 TOPS | 2/4/8 GB | 2× M.2 (PCIe 2.0 x2 NVMe), 2× 1 GbE, Wi-Fi 5 + BT 5.0 | 26-pin | USB-C 5 V / 5 A |

## 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.

## Claims

- The Orange Pi 5 Max and Orange Pi 5 Pro use LPDDR5 memory and a 40-pin expansion header, and their product pages specify a 5 V / 5 A USB-C power supply. (unverified)
- The Orange Pi RV2 uses the Ky X1 8-core RISC-V processor and its product page lists Ubuntu 24.04 as the supported OS. (unverified)
- The Orange Pi 5B adds a Wi-Fi 6 + Bluetooth 5.3 module and 32/64/128/256 GB of eMMC to the Orange Pi 5; both use the Rockchip RK3588S and a 26-pin expansion header. (unverified)
- The Orange Pi 3B uses the Rockchip RK3566 with an NPU of 0.8 TOPS at INT8. (unverified)
- The Orange Pi 5 Plus has two 2.5G Ethernet ports (RTL8125BG) and an M.2 M-key slot for NVMe SSDs with PCIe 3.0 x4. (unverified)
- The Orange Pi 5 Plus and Orange Pi 5 Max use the full Rockchip RK3588, while the Orange Pi 5, 5B, 5 Pro and CM5 use the RK3588S. (unverified)
