No Name Description
5 J7
– JTAG connector
Connector for the IAR I-jet JTAG Debugger
Note: Pin 7 of the I-Jet debugger cable is keyed with a white
plug so pin 7 must be removed from the EVB.
6 S2
– Factory reset button
Factory reset button using GPIOA_7.
To enable this button, set Pin 2 of SW4 to ON and press the
button for more than 5 seconds to initialize
nvram
data.
7 S1
– WPS button
WPS button using GPIOA_6.
To enable this button, set Pin 1 of SW4 to ON and press the
button to start WPS mode.
8 SW5
– RTC_WAKE_UP switch
Switch to wake up the board from sleep mode.
9 SW6
– RTC_PWR_KEY switch
Switch to turn the EVB ON and OFF.
10 P1
– External VDD
External VDD (3.3V) can be supplied to the P1 pins.
For normal operation, this jumper should be shorted.
10
P2
– Jumper to measure
current consumption of the
DA16200
Pin for current measurement.
For normal operation, this pin should be shorted.
- Pull out the Short Pin cap and use jumper wires to
connect to the measuring equipment.
11 SW1
– GPIO selection switch
GPIO selection switch, default OFF, see Table 2
below.
12 SW2
– GPIO selection switch
GPIO selection switch, default ON, see Table 2
below.
13 SW3
– GPIO selection switch
GPIO selection switch, default ON, see Table 2
below.
14 SW4
– GPIO selection switch
GPIO selection switch, default ON, see Table 2
below.
15 SW7
– UART0 selection switch
UART0 selection switch, default ON, see Table 2
below.
16 J3, J4
– External Connector
Provides access to all pins of the DA16200MOD for testing and
debugging.
