OLED1 Xplained Pro extension header
OLED1 Xplained Pro implements one
This header makes it possible to connect the board to any Xplained Pro MCU board. The pin-out definition for
the extension header can be seen in

Peripherals
LEDs
There are three yellow LEDs available on OLED1 Xplained Pro. The LEDs can be activated by driving the con-
nected I/O line low.
Table 4.2. LED connections
Push buttons
There are three push buttons available on OLED1 Xplained Pro. When a button is pushed the corresponding
IO pin is connected to ground. There are no external pull-up resistors on OLED1 Xplained Pro, so internal pull-
up resistors have to be enabled in the target microcontroller.
