6.4 CON1 and CON2 pads
The GPIO pins are led out to CON1 and CON2 pads situated on the both sides of the board. They
allow the user to attach additional hardware, check readings or perform hardware debug. The
“Pin#” column shows connector number and does NOT represent the naming on the bottom of the
board. The table is divided into two big columns and explains the pin of both the connectors CON1
and CON2.

“Pin#” column shows connector number and does NOT represent the naming on the bottom of the
board. The table is divided into two big columns and explains the pin of both the connectors CON1
and CON2.
There are three color sections in the table below. Each color represents signals needed to establish a
specific connection and functionality like in the MAXI and the MINI versions of the board. The
GREEN section (CON2 – Pin#3 to Pin#11) marks the signals needed to make UEXT (check the
schematics of OLinuXino-MAXI or OLinuXino-MINI or the UEXT section above for further help).
The YELLOW section (CON2 - Pin#12 to Pin#15) marks the signals needed to build SJTAG. The
BLUE section (CON2- Pin#16 to Pin#21) shows the signals needed for audio in and audio out.
