] On, 4 lights on the ordinary line.

Bug: USB-A to C will also have 5 lights, but the CC light is darker. The reason is that the CC stored in the C port plug is grounded, and then the cc light and the GND light are connected in series on the detection board. ,It does not affect the use of. This board is useless. 23333

does not have a Lightning socket, so it cannot be soldered. Spending money to buy it separately defeats the original purpose, but it cannot be left without it. The seat must be free.
