Header J4 Arduino pin Connection on
CYW20819 WICED Enum
name Description
7 D1 P32 WICED_P32 PUART RX
8 D0 P37 WICED_P37 PUART TX
Table 15 Header J1 pin configuration
Header J1 Arduino pin Connection on CYW20819 Description
1 NC NC NC
2 VIO_BASE VDDIO I/O reference pin used by shields to determine
the I/O voltage. Connected to VDDIO on this
board. Therefore, IOREF follows 1.8 V or 3.0 V,
or VCOIN of VDDIO.
3 RST ARD_RST/P1 Arduino Reset (R72 install position A) (See
Device reset ) / P1 (R72 install position B).
4 3V0 VDD3P0 3.0-V supply output to the Arduino Shield.
5 5V VDD5V 5-V supply output to the Arduino Shield.
6 GND GND Ground
7 GND GND Ground
8 NC NC NC
Table 16 Header J2 pin configuration
Header J2 Arduino pin Connection on
CYW20819 WICED Enum
name Description
1 A0 P8 WICED_P08 GPIO/Thermistor
2 A1 NC - -
3 A2 P10 WICED_P10 GPIO/PUART CTS
4 A3 NC - -
5 A4 P12 WICED_P12 GPIO
6 A5 P13 WICED_P13 GPIO
Note: When accessing Arduino pins, remove the jumpers that may interfere with the Arduino pins such as
PUART jumpers and thermistor jumper.
2.5 Other headers
J11 and J12 are test headers which bring out certain pins of CYW20819 for testing.
