Dallas 1-Wire:
The  Dallas  1-Wire  protocol  is  a  form  of  serial
communications designed to operate over a single
data  line  plus  ground  reference.  Multiple  1  Wire
devices  can  be  attached  to  the  same  shared  data
line  to  network  many  devices.  One  wire  device
support  is  available  on  both  the  IO1  and  the  IO2
pins on the uOLED-96G2 module.

The  following  diagram  depicts  a  typical  1-Wire
temperature sensor interface.

Sound Output:
The uOLED-96G2 module is capable of generating
complex sounds and RTTTL tunes from its IO1 and
IO2 pins. A simple speaker circuit as shown below
can be utilised.

System Pins

4.3.

+5V (Module Voltage Input)
Pin 1:
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.

5V Out (~4.7V)
Pin 2:
External  circuitry  that  requires  approximately  5V
supply  can  be  powered  up  via  this  pin.  Maximum
available current is 50mA.

GND (Module Ground)
Pins 7, 8:
Device ground pins. These pins must be connected
to ground.

RESET (Module Master Reset)
Pin 9:
Module  Master  Reset  pin.  An  active  low  pulse  of
greater  than  2  micro-seconds  will  reset  the
module.  Internally  pulled  up  to  3.3V  via  a  4.7K
resistor.  Only  use  open  collector  type  circuits  to
reset the device if an external reset is required.

3.3Vout (3.3V Regulated Output)
Pin 10:
External  circuitry  that  requires  a  regulated  3.3V
supply  can  be  powered  up  via  this  pin.  Maximum
available current is 50mA.
