All of the available GPIO pins in the daughter cards (those not already used for existing EVB peripherals) are routed at the
GPIO matrix. The matrix provides an easy to follow, intuitive, space saving grid of 0.1” header through hole pads. Users can
solder wires, fit headers or simply insert a scope probe into the respective pad.
To use the matrix, simply read the port letter from the top or bottom row of text then the pad number from the columns on the
left or right of the matrix.

11.3 User switches
There are four active high pushbutton switches (SW2, SW3, SW4, and SW5), pulled low, driven to 3.3 V or 5.0 V by the
PER_HVA rail. The switches are connected to a header (J27), and also directly wired to MCU ports so no wires need to be
wired, unless it is required to route these to a different GPIO pad on the MCU.
11.4 User LED’s
There are four LEDs for general purpose (D10, D11, D12, and D13), pulled to 3.3 V or 5.0 V by the PER_HVA rail. The
LEDs are connected to a header (J28), and also directly wired to MCU ports so no wired need to be wired, unless it is
required to route these to a different GPIO pad on the MCU.
