Based on the Chinese and English RK3588 Hardware Design Guide V1.3 (2023-02-13), for reviewing SoC boards and carriers. AIM7 and LM7 carriers must follow module interface definitions; Sige7 provides a starting point for software and peripheral validation. SoC capabilities are not a board connector list. Verify SDK/BSP, kernel, board revision and firmware. Values are source references, not ArmSoM hardware measurements.

Allocate by sensor and PHY
The guide prefers dedicated MIPI DPHY CSI RX. Each of the two interfaces supports four lanes or two two-lane groups with the correct clocks. D/C Combo PHYs have additional mode restrictions; spare pins do not allow arbitrary combinations. Check sensor format, rate, power, reset, MCLK and I2C before choosing connectors.
CIF levels and system validation
CIF spans VCCIO5/VCCIO6; both supplies must agree with sensor IO, including I2C pull-ups. MIPI wiring does not establish BSP sensor support: drivers, device tree and ISP configuration are still required. Start with one stream, then validate the target multi-stream mode, sustained operation, dropped frames, clock stability and temperature.

ArmSoM development path
AIM7 supports compute-module carrier development, LM7 targets LGA module integration, and Sige7 supports early software and peripheral evaluation. With modules, identify which supplies, DDR and boot circuits are already integrated before designing the carrier. Do not duplicate SoC reference circuits unnecessarily. Follow product documentation for connectors, exposed interfaces, voltages and system support.
