CN1 connects directly to a USB host or HUB port, or can be connected to a USB extension cable. This
connects to USB signals, 5V USB Bus power and GND. When connecting the module to a USB host or HUB
the signal pads should be facing upwards when connecting to a horizontal connector and be facing right
for vertical connectors. If the module is plugged in upside down no connectivity will be made between
PCB and HUB, no damage will occur from plugging the module in the wrong way.

Description
5V Power input USB port. For a low power USB bus powered design, up to 100mA can
be sourced from the 5V supply on the USB bus. A maximum of 500mA can be sourced
from the USB bus in a high power USB bus powered design.

Description
UART transmit data
5V Power output USB port.
Module Ground Supply
Can be used by an external device to reset the FT234XD.
UART receive data
3.3V output from FT234XD integrated LDO regulator. This pin is decoupled to ground
on the module PCB with a 10nF capacitor and offers 3V3 at up to 50mA for external
hardware.
