BT-UART
The BT-UART has the same properties as the FF-UART, however
only the signals BT_RxD, BT_CTC and BT_RTS are supported. The
TTL signals RXD and CTS can be separated from the RS-232
transceiver at U42 with Jumper JP2 set to 3+4 and 5+6. The RS-232
transceiver is located on the Development Board.
