PIO Expansion
+3V 3
The SAM3U4E product features 3 PIO controllers, PIOA, PIOB and PIOC, which multiplex the I/O lines
of the peripheral set. Each PIO controller controls up to 32 lines. Expansion ports J13, J14, J15 provide
a way for customers to define any PIO channels.
All the expansion port pins are directly connected to the SAM3U4E chip, except PB4 and PB5, which are
assigned as AD12BAD3 and AD0 by default on the board. Solder drops have been implemented on the
board to avoid signal conflicts from traces routing to expansion ports. If PB4 and PB5 need to be con-
nected to the J14 connector, solder drops SD3 and SD4 should be shorted.
