USB I/O 24 R Datasheet
Hardware Configurations outlined on the schematic for the USB I/O 24 R
The USB I/O 24 R has a number of different hardware configurations that can be implemented.
Each of the configurations are listed below:
Bus Powered (FTDI Chip)
The bus powered mode draws power from the USB Bus. This option is the current configuration
that is used when the USB I/O 24 R is sent out.
Self Powered (FTDI Chip)
The self-powered mode of operation draws power from its own external Power supply and doesn’t
draw any current from the USB Bus.
Note: The FTDI chip can only be bus powered or self powered
Powering SX 48 Options
There are a number of different ways that the UBICOM SX48 micro controller can be powered.
These various options are shown below.
Note: When the SX48 is powered from the USB this also means that the USB Bus will also power
the FTDI FT245BM.
USB 5V
The SX48 draws it power from the USB Bus.
USB 3.3V
The SX48 draws it power from the USB Bus, but a 3.3V regulator regulates the voltage provided by
the USB. Note: This 3.3V regulator is not currently placed on the board and is only provided as a
separate option.
External 5V
The SX48 draws it power from its own external power supply
External 3.3V
The SX48 draws it power from its own external power supply, but the voltage provided by the
power supply can be either set to the desired 3.3V or regulated by a 3.3V regulator. Note: This 3.3V
regulator is not currently placed on the board and is only provided as a separate option.
