====== RS-232 level ====== It is best to connect to carambola using standard RS-232 male cable. Just plug cable to carambola, set 115200 8N1 settings without hardware flow control and power up your carambola. ====== TTL 3.3V level ====== However, if you have TTL level USB to serial converter, you should do some soldering. Remove J9 and J10 jumpers and connect FTDI 3.3V TTL serial to USB cable. J9.1 – RX(input), J10.1 – TX(output). I used FTDI 3.3V USB to serial converter. {{:carambola_where_to_start_3.jpg?nolink& |}} ====== Software ====== You can use any [[carambola_serial_terminal|terminal]] program you wish to communicate.
