Transferring thoughts to your world

I needed an RS-232 USB dongle that would work with an android phone and found an old LG phone USB cable hanging about. A bit of poking revealed it to simply be a PL-2303 serial adapter. Lopping off the connector on the end and putting some 1 pin sockets on the ends results in a quite usable 3.3v serial dongle.

The color code is:

GND – Brown and shield
txd – red
dtr_n  – grey
rts_n – violet
rxd – orange
ri – green
dsr_n – nc
cts – blue
dcd_n – yellow
