Table 3.1 UB232R Module Connection
The signal output level on connectors J1 and J2 are controlled by the voltage supplied to the VCCIO pin 4
on the FT232R. The VCCIO is selected between the +5V (VCC from USB) or the output of the FT232R Low
Drop Out (LDO) +3.3V regulator. The VCCIO selection is done by fitting a link on connector J3. The
selection is shown in Table 3.2.
