Datasheet

OLIMEX© 2012 OLinuXino-MAXI user's manual
ones filled with “Not implemented” doesn't have Linux support by the time of writing and will be
updated overtime. “Linux GPIO” is the one you should use in Linux (the one in the datasheet);
“OLinuXino name” is the pin as written on the bottom of the board. ”OLinuXino GPIO Connector
#” is the consecutive number of pins with BAT being Pin#1 and GND#40.
Note that if “OLinuXino Name” starts with P and then is followed by a number X, the PX is the
name written on the bottom of the board (under the connector) with white ink. If “OLinuXino
Name” is other text it is a signal used for the hardware of the board but still can be controller by the
Linux (it can't be found at the GPIO connector though).
