Pin Headers
The pin headers at the top side can be used to setup connections between modules and pos-
sible on board peripherals. Thus, pin headers having signal names at their left side only, name-
ly the pin headers AUDIO, CONTROL, ASC0_A, ASC0_B, DAI, ASC1, GPIO, and PWR, can
be bridged by jumpers. All of these pin headers have the module's signal name on their left side
(marked yellow in
), whereas the right side corresponds to peripherals like level shifters
or the DSB connector (marked green in
•
Placing a jumper connects a line through a level shifter to the associated pin at the 2x40 pin
connector at the underside of the LGA DevKit (and thus to a connected DSB75/DSB-Mini).

Not placing a jumper leaves a module signal open.
External periphery can also be connected to all accessible module signals directly. When con-
necting other external periphery to the pin headers pay attention not to violate the maximum
module ratings.
