I/O Headers
4.2.6.1
Arduino-compatible Headers (J1, J2, J3, J4)
The board has four Arduino-compatible headers:
J1
,
J2
,
J3
, and
J4
. You can connect 3.3 V Arduino-
compatible shields to develop applications based on the shield’s hardware.
Note:
5-V shields are not supported and connecting a 5-V shield may permanently damage the
board.
Note:
All Arduino header pins are not connected to the same voltage reference. ARD_D[10:13] are
powered by VDDIO0 whereas rest are powered by domains connected to VTARG. Hence Arduino
shields particularly that use ARD_D[10:13] must not be used when VTARG is 1.8 V.
4.2.6.2
PSoC 64 MCU I/O Headers (J21, J22, and J24)
These headers provide connectivity to PSoC 64 MCU GPIOs that are not connected to the Arduino-
compatible headers. The majority of these pins are multiplexed with onboard peripherals and are not
connected to the PSoC 64 MCU by default. They can be connected to the PSoC 64 MCU using
0-ohm resistors.
4.2.6.3
WL/BT I/O Headers (J23)
These headers provide connectivity to a few of the CYW4343W GPIOs that are available at the
castellated pads. All these I/Os work at the VDDIO_WL voltage (1.8 V by default).
