The RK3588 board-to-board development board aims to enable flexible combinations between the core board and functional sub-boards ( carrier board) by adopting a modular design and using standardized interfaces (e.g., PCIe, MXM, high-speed board-to-board connectors)
When compared to integrated board or single board computer, board- to -board motherboard shares the following core advantages:
| Advantage | B2B Development Boards | Traditional MCU Boards |
| Expandability | Modular, hot-swappable | Fixed peripherals, jumper wires |
| Signal Quality | Supports GHz-level signals | Limited to low- speed GPIO/UART |
| Development Speed | Reuse validated modules | Requires full hardware redesign |
| Use Cases | Complex systems (AI/industrial) | Simple control (sensor logging) |
