Well I've been mapping the pins today and I found out what happened to the fourth UARTUSART. It seems that it's alive and well and available on pins 65 and 52.

Where the heck is pin 65 I hear you ask? Looks like it's A11, I'll post the latest pinout diagram soon.

So the Due has 5 hardware serial ports, 1 for the USB and 4 for the user.

However it doesn't appear to be officially supported yet.

USART uses minimum 3 pins right? MISO, MOSI and SCK. Are the third pin there too?

Graynomad

Only if used in SPI mode. Normally it's just a UART like any other with RxD and TxD.

I'll look into whether the SCK pin is there as well.

I checked, SCK2 is not connected on the SAM, so out of luck there.
