Design Notes
- Integrated 64 MB DRAM removes external memory from the BOM.
- Display is HD + VGA only; for CVBS output see A210 or A211C.
- The official product page does not list video input; choose A210 or above if camera or digital video input is required.
- Confirm with official SDK, reference designs, and prototype validation before production.
