IO5/BUS_WR pin (GPIO IO5 or BUS_WR pin):
General Purpose IO5 pin. Also used for BUS_WR
signal to write and latch the data to the parallel
GPIO BUS0..BUS7.
BUS0-BUS7 pins (GPIO 8-Bit Bus):
8-bit parallel General purpose I/O Bus.

+5V (Module Voltage Input)
H1 pin 14, H2 pin 10:
Module supply voltage input pin. This pin must be
connected to a regulated supply voltage in the
range of 4.0 Volts to 5.5 Volts DC. Nominal
operating voltage is 5.0 Volts.
3.3V Out (3.3V Regulated Output)
H1 pin 22:
External circuitry that requires a regulated 3.3V
supply can be powered up via this pin. Maximum
available current is 20mA.
GND (Module Ground)
H1 pin 11/13, H2 pin 4:
Device ground pins. These pins must be connected
to ground.
RESET (Module Master Reset)
H1 pin 20, H2 pin 2:
Module Master Reset pin. An active low pulse of
greater than 2μs will reset the module. Internally
pulled up to 3.3V via a 10K resistor. Only use open
collector type circuits to reset the device if an
external reset is required.
AUDENB (Audio Enable Output)
H1 pin 18:
Output dedicated to enable or disable an external
audio amplifier (if required).
AUDIO (Audio Line Level Input/Output)
H1 pin 16:
Line Level output specifically for Audio. This pin is
for connecting to an external amplifier. When used
in conjunction with AUDENB this pin can be used
as a line-level output (AUDENB enabled) to drive
an external amplifier.
Note: All GPIO pins are 5.0V tolerant.

The μVGA-III features a remote VGA connector,
which is able to be disconnected from the PCB. The
remote VGA connector enables flexible mounting
and connection options when using the μVGA-III.
Note: The orientation of the VGA cable onto the
PCB is important. The striped wire on the VGA
cable indicates Pin 1 on Header J3.
Extra Video Out pads are provided on the rear of
the PCB (J4), for added flexibility and wiring
options.
Note: The extra Video Out pads (J4) are a mirror
image to the header on the front of the PCB (J3),
so the supplied VGA cable cannot simply be
plugged in if a header is attached.
