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.

Simulation is not module temperature rise
Table 4-1 comes from a specified package and JEDEC finite-element PCB model: 101×114mm, 1.6mm, ten layers, no heatsink. Do not apply it directly to AIM7, an LM7 carrier or a Sige7 enclosure. θJA, θJB and θJC use different reference points and are not interchangeable heatsink inputs.
Validate thermal paths and protection
Check die-to-interface, heatsink, enclosure and ambient paths, mounting pressure and electrical isolation. The 20–50mm RK3588/RK806 spacing is a board reference, not an instruction to modify module internals. Test sustained workload, frequency, temperature and application latency with the actual BSP thermal policy; disabling protection does not demonstrate performance.

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.
