| | Codename / PCB | Memory | Common Firmware Type | | ---------------- | ------------------------ | ----------- | ------------------------ | | EC6108V9 | CA (CA9) / CA9V9 | NAND / eMMC | Hi3798M | | EC6108V9C | CA (V9C) | eMMC | Hi3798M | | EC6108V9U | CA9U / V9U | eMMC | Hi3798M | | EC6108V9A | CA9A (rare) | NAND | Hi3798M | | EC6108V9E | CA9E | eMMC | Hi3798M |
