Table 21:
Pin Assignment of PHYTEC Expansion Connector X69
8
:
These pins are configured as GPIO pins. To use them as UART interface the pin muxing must be changed and additional
software development is required.
9
:
Jumpers J72 – J75, J79 and J80 allow to configure the USB interface at the expansion connector (
Table 14
).
10
:
Caution!
There is no protective circuit for the USB interface brought out at the expansion connector X69.
11
:
Voltage level is not specified and depends on the connected power module and the voltage attached.
