Description
VBUS – USB Power provided from upstream USB Host or Hub
D – = USB data signal, negative polarity
D+ = USB data signal, positive polarity
ID = Host /slave select pin ,No used
GND = USB signal ground
Drain = typically connected to the host PC case
Table 3.1 – USB "miniB" Receptacle Pin-Out
3.1.2 RS232
The RS232 port is configured as Data Terminal Equipment (DTE), with a 9-contact D-Sub Pin connector.
Pin assignments are according to TIA/EIA-574 which formally defines the assignments for a COM port
found on many personal computers.
