Product User’s Manual – UC00C
VCC selectable Switch
VCC at “F” is voltage option to determine the TTL level of UART interface pins. UC00C to
microcontroller. User may choose either 3.3V or 5V. If 5V is chosen, all the interface pins
which include TX, RX, DTR, CTS, RTS, DSR will be in 5V TTL logic. On the other hand, if
VCC at “F” is 3V3, all interface pin will be in 3.3V TTL logic.
