4.4 Buttons
The PT7682W/PT7686W-SAOPTC0 HDK is equipped with buttons with the following
functionality. The push buttons are shown in Figure 2.
1). System reset button (S2001) resets the MT7682 HDK.
2). External interrupt button (S2005). Users can configure GPIO0 as an external interrupt
pin. Press the button to wake up the system from the sleep mode.
3). External interrupt button (S2006). To enter RETENTION mode is software configurable
and to exit, use RTC timer or EINT.
4.5 Extension Connectors
The PT7682W/PT7686W-SAOPTC0 HDK provides similar pin-out extension connectors
(J2101 and J2103) for various sensor and device connectivity, as shown in Figure 2 and
described in Table 4.
The board has 14 GPIOs multiplexed with other interfaces. Depending on the use case,
user can configure each I/O functionality.
