6.1. Switches
There are four switches located on the board. The function of each switch and its connection are shown in Table 6-1.
*Refer to schematic for detailed connectivity information.
6.2. LEDs
There are six LEDs on the CPU board. The green ‘POWER’ LED lights when the board is powered. The orange ‘BOOT’ LED indicates the
device is in BOOT mode when lit. The four user LEDs are connected to an IO port and will light when their corresponding port pin is set low.
Table 6-2, below, shows the LED pin references and their corresponding microcontroller port pin connections.
6.3. Potentiometer
A single turn potentiometer is connected to AN8 (P1.0) of the microcontroller. This may be used to vary the input analog voltage value to
this pin between VREF and Ground.
