无法使用5盘hat | Can not buy Penta SATA HAT for 5a in China
See this thread: Will there be a SATA Hat for the ROCK 5?
The Penta Hat was added to the E-Key slot of a 5B, so it might be work with the slot on the 5A…
While Allnet.china said “Rock5 Model A - please choose the right option” there seems to be no option to choose, so it might be necessary to order the adapter additionally… Anyway, ask Allnet.china, they typically answer quickly.
