· 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.
Using the NPU on RK3588/RK3566 Orange Pis: RKNN-Toolkit2 on the PC, RKNN-Toolkit-Lite2 or the C runtime on the board

· The 6 TOPS NPU of the Orange Pi 5 family (and the 0.8 TOPS NPU of the 3B) is used through Rockchip's RKNN stack: convert your model to .rknn with RKNN-Toolkit2 on a PC, then run it on the board with RKNN-Toolkit-Lite2 (Python) or the RKNN Runtime C API. Old RKNN-Toolkit (v1) models don't work.
