USB2ANY Header
USB2ANY is TI MCU-based adapter intended to allow a computer to control an electronic evaluation
module (EVM) via a USB connection. In this design, the I
2
C interface of USB2ANY is used to externally
monitor, control, and or re-program the internal registers of PMIC. The wiring of the USB2ANY header is
shown in

Functional Switches and Status LEDs
There are two functional multi-purpose push buttons connected to GPIOs configured as inputs on the
processor that can be used for software developers to test applications developed using this board. Three
LED are connected to three GPIOs of the processor to indicate the status of processes that are running,
completed, or may have failed. Both the push-buttons and status LEDs can be used for debugging or to
provide tactile inputs and visual feedback to the user. These connections are shown in
.

GPIO Expansion Connector
All un-used GPIO pins on the i.MX 6ULL processor are routed out to an expansion header, which is also
capable of providing 1.8 V, 3.3 V, and 5 V to a daughter card PCB.
