• Clarify whether “4G” = 4 GB RAM or 4 GB storage (eMMC/Flash). Misinterpretation affects performance expectations.
• Confirm which memory is 512M (RAM vs. flash).
• Verify existence/absence of recovery/SOS mechanism if reliable remote recovery is needed.
• Confirm exact peripheral set (HDMI, USB, Ethernet, Wi‑Fi/BT, GPIO pinout) before purchase or integration.
• Check power requirements and enclosure/thermal specifications.
• Confirm software/driver support and community resources for the specific Aml920 revision.
