But I have bad news. Both UARTs can be connected to pairs(tx+rx) 14+16, 32+33, 40+41 and both UARTs can be connected to any of this pins. But only 14, 16 and 40(PWM0) wired to ext.pin. > > > On Tue, May 14, 2013 at 10:24 AM, Aleksandr Rybalko > wrote: > > > On Tue, 14 May 2013 09:06:44 -0700 > > Adrian Chadd wrote: > > > > > ... the r-pi actually has an RS232 port exposed via GPIO.
